DLR Advances Crack Prediction in Ceramic Matrix Composites Using MultiMech

Research Will Considerably Reduce Development Time of Novel CMC Materials

Omaha, Nebraska: The German Aerospace Center (DLR) has selected MultiMechanics, a developer of multiscale modeling and simulation software for advanced materials, to perform advanced crack prediction during the manufacturing of ceramic matrix composite (CMC) components.

The simulation group at DLR’s Institute of Structures and Design in Stuttgart has recently begun to model the process of pyrolysis, an intermediate step in production of ceramic matrix composites. Within this process, carbon fiber reinforced polymers (CFRP) are heated to temperatures up to 1,600 degrees Celsius and then cooled down. The team wants to understand how temperature change would affect the material’s microstructure and consequently the material behavior. This analysis is crucial for future CMC components produced by DLR, including nozzles for rockets and thermal protection systems for re-entry vehicles amongst other applications.

“MultiMech allows us to model microstructural cracks and determine how they would affect the overall composite part,” states Neraj Jain, Group Leader in Simulation and Engineering at the Department of Ceramic Composites and Structures at DLR. “Thanks to it, we can actually see where a crack is developing, how the crack will change our material, and how it will affect the final microstructure of the material.”

Using MultiMech, the engineers can vary the interface strength between fiber and ceramic matrix and evaluate how this parameter would influence crack initiation and propagation. This insight enables them to optimize the material and tailor it according to microstructural mechanics – a crucial step to more accurately understanding how a part will behave as a whole.

“DLR is a global leader in aeronautics and space research and we are extremely proud to support their advancement in understanding and designing CMC parts,” stated Dr. Flavio Souza, President  & CTO of MultiMechanics. “Our work at MultiMechanics for the last ten years has been dedicated to accurately connecting microstructural behavior of advanced materials to the overall part performance and its manufacturing, and we are pleased to see that our users are seeing the benefits and high value of TRUE multiscale modeling.”

“MultiMech’s efficient integration with our other FEA tools like Abaqus and ANSYS increases our productivity and brings us closer to our aim to optimize CMC material virtually,” stated Jain. “The way we are able to conduct crack modeling and multiscale simulation holds lots of opportunities in many projects to come.”

MultiMech 19.0 Delivers Expanded Simulation Capabilities and Increased Speed

Release Improves Breadth and Run Times of Multiscale Composite Simulations

Omaha, Nebraska: MultiMechanics, a developer of multiscale composite modeling and simulation software, has announced the release of MultiMech 19.0.

Composite materials are currently transforming the transportation industry by improving efficiency, lowering emissions, and decreasing fuel consumption. However, the current process for adopting these advanced materials is time sensitive and can cost millions in testing and certification. To help address these challenges, MultiMech 19.0 delivers new material models, new damage scenarios, faster run times, and expanded integration with commonly-used FEA systems.

Highlights of this release include:

New bi-modulus elastic model

This addition will enable engineers to better capture the mechanical behavior of carbon fibers. In addition to exhibiting nonlinear elastic behavior at small deformation, carbon fibers also possess different mechanical properties in tension and compression, making them especially difficult to model and simulate. MultiMech 19.0 allows engineers to more realistically predict the behavior of these materials.

Solver speed-up of 1.5x

The solver speed-up will allow engineers to take advantage of the accuracy of a concurrent multiscale approach while benefiting from increased speed.

Parallel runs in Optimizer

This will allow engineers to reduce the runtime of DoE jobs using MultiMechanics’ Optimizer and get answers faster.

New material models

MultiMech 19.0 implements new material and failure models, including continuum damage models for orthotropic materials and new damage laws that will allow users to capture unique material behavior with higher accuracy.

Enhancements to nonlinear solver

MultiMech 19.0 features improved automated time step and optional displacement convergence check, as well as the ability to check for large displacements in the nonlinear solver.

Material Database

The MultiMech material database has been redesigned and enhanced to speed up the workflow. Users can now create their own database of material cards to be used with MultiMech, including material definitions for individual constituents, as well as define an entire Representative Volume Element as an entry to the material database. It is also very easy to create, import, export and share a material database with other users within an organization.

Virtual DMA

MultiMech 19.0 includes a streamlined tool to run Dynamic Mechanical Analyzer (DMA) tests virtually. With this tool, users can easily and quickly characterize the viscoelastic behavior of complex microstructures in all directions, at different temperatures and frequencies.

ANSYS DX Integration

With the new ANSYS DX integration, users can perform Optimization studies at both the macro and micro scale using ANSYS DX’s unique capabilities.

“As the use of material modeling and simulation software expands, material scientists are demanding more accurate results without compromising speed and functionality, as well as easier and more integrated workflows. MultiMech 19.0 marks the significant progress we have made towards closing that gap,” stated Dr. Flavio Souza, President & CTO of MultiMechanics.

MultiMechanics and Opterus R&D Partner to Create Advanced Material Models in Response to NASA Solicitation

Collaboration Will Advance Knowledge of Thin-Ply High Strain Composites for Space Applications

Omaha, Nebraska: MultiMechanics, a developer of multiscale composite modeling and simulation software, and Opterus R&D, a Colorado-based satellite component manufacturer specializing in the design and testing of deployable space structures, have announced a collaboration in response to a NASA Solicitation seeking further exploration of the use of thin-ply High Strain Composites (HSCs) for space applications. These advanced composites have the potential to reduce weight and increase the performance of space systems, but they exhibit behavior that is difficult to predict using currently available Finite Element Analysis (FEA) tools.

Thin-ply HSCs are being used by Opterus in several commercial, NASA and DoD missions that achieve unprecedented packaging and deployed stiffness performance. Compared to traditional composites, HSCs exhibit improved damage tolerance, resistance to microcracking, improved aging and fatigue resistance, reduced minimum-gage thickness, and increased scalability.

However, HSC materials behave in a complex manner that is difficult to predict. Strain levels in HSCs are up to 3x higher than in traditional composites, causing behaviors that are nonlinear with fiber tensile stiffening and compression softening and sensitive to creep and stress relaxation. Expensive, iterative physical testing is currently being used to study the loading-deformation and failure response of HSCs. The MultiMechanics – Opterus collaboration will develop accurate, validated, and usable software to predict the behavior of HSC structures.

In response to a NASA Solicitation and in order to accelerate the adoption of HSCs for space applications, Opterus R&D will create material models of HSCs that can be used in currently-available FEA systems. MultiMech will be used in this development due to its unique capabilities to model rate-dependent material behavior, a critical feature presented by HSCs.

“MultiMechanics offers the most computationally efficient material modeling platform, along with the broadest range of material options,” stated Dr. Thomas Murphey, President at Opterus R&D. “In addition to the advanced capabilities of their software, the MultiMechanics team has also shown an interest in and willingness to support the growing HSC community.”

Phase I of the program is to generate test data, exercise the current commercial version of MultiMech, and identify the best path forward to confirm that MultiMech can address all HSC analysis needs in the future. In Phase II, MultiMechanics will take a larger role aimed at implementing features specific to solving HSC engineering challenges.

“HSCs exhibit high potential for reduced weight and increased performance for several space applications,” stated Dr. Flavio Souza, President & CTO at MultiMechanics. “We are proud to support Opterus R&D and the entire HSC community in their mission to accelerate the adoption of these promising materials.”
