/MAT/LAW200 (MDS)
Block Format Keyword This law is a link to Multiscale Designer material law.
This material is not compatible with failure models, viscous model or thermal options. All damage and failure are defined inside of the material directly. This material is compatible with shell and any solid elements.

Comments
- This material law is a direct input to Radioss for the Multiscale Designer material law. Information about the contents of the different files is available in Multiscale Designer Reference Guide.
- /MAT/LAW200 (MDS) is available to connect Radioss with Multiscale Designer to include a much wider range of different material models.
- Multiscale Designer is an efficient tool for development and simulation of multiscale material models of continuous, woven, and/or chopped fiber composites, honeycomb cores, reinforced concrete, soil, bones, and various other heterogeneous materials.
- Applications include multiscale
material modeling for design, ultimate failure, statistical- based material
allowances, fatigue, fracture, impact, crash, environmental degradation, and
multiphysics simulations.
- Developed multiscale material models using forward homogenization and inverse optimization technologies.
- Built-in parametric unit cells for unidirectional, woven, chopped, and particulate fiber composites.
- Simulate nonlinear material behavior including ultimate failure at the micro-scale.
- Obtain virtual material allowances supported by test and perform fatigue analysis.
- Efficient plug-ins to commercial FEA codes OptiStruct and Radioss.
- If the /MAT/LAW200 (MDS) entry is specified, Radioss will search for the Multiscale Designer installation within the same Mechanical Solvers installation from which the Radioss run is initiated. The MDSDIR I/O Options Entry can also be used to specify the Multiscale Designer installation location, if it was installed in a different location.
