Altair Multiscale Designer is an efficient tool for the development and simulation of multiscale material models of solid fiber composites, woven and / or cut, alveolar nuclei, reinforced concrete, soil, bones and various other heterogeneous materials.
Applications include multi-scale material modeling for design, final failure, material based on allowed statistics, fatigue, fracture, impact, collision, environmental degradation and multiphysical simulations, and provides plugins for FEA Optistruct, RADIOSS, LS-DYNA, and Abaqus commercial solvers.
Benefits
While there are multiple modeling structures at various scales, Multiscale Designer provides an unparalleled combination of practicality, mathematical rigor, validation, and versatility.
Practicality
Multiscale Designer is equipped with a systematic model reduction technology that reduces complex unit cells, with hundreds of thousands of finite elements, to a manageable number of deformation modes and state variables. Optimal kinematics (modes and state variables) is automatically selected to provide the desired level of accuracy for amounts of interest.
Multiscale Designer is equipped with an extensible parametric library of automatically generated unit cell models using CAD and integrated mesh tools that enable optimization and stochastic simulations. The current parametric library of unit cell models includes; fiber, fabrics, short and long fiber cut, ordered particles and random microstructures of particles. This eliminates the overhead of generating complex models of unit cells and their connection to FEA macroscale solvers. In addition to the parametric library of unit cells, user-defined unit cell models (CAD mesh and/or FEA) can be imported and/or generated entirely in Multiscale Designer.
Mathematical Rigor
Multiscale Designer is scale-free and provides mesh-insensitive results inherent to competing products on multiple scales. The characteristic scale of the material length is automatically identified by the Multiscale Designer based on the experimental data specified by the user at the coupon level.
Multiscale Designer is equipped with multi-scale stochastic features that convert geometric and material uncertainties into component uncertainties at the macro level.
Validation
Multiscale Designer is integrated into an experimental material database and a multi-step optimization mechanism that identifies model parameters with a high degree of uncertainty (such as void content, microcracks, interface/ interphase properties).
Versatility
The advanced features of Multiscale Designer include; generation of material properties allowed in bases A and B with minimal testing without compromising accuracy, microstructural optimization, multiscale fatigue and multiphysics at multiple scales.
Resources
Multiscale Designer - Mechanical
Mechanical is based on a micromechanical approach that has a minimum number of internal variables that represent the inelastic deformation of microphases and their interfaces. Resolves microscale fields at a computational cost comparable to macroscale modeling. Multiscale Designer - Mechanical precalculates a database of materials, such as transformation influence functions, in the preprocessing stage before nonlinear analysis, which is subsequently reused in nonlinear analysis. Multiscale Designer - Mechanical has been validated against more than 50 benchmark issues at coupon and component levels with various forms of composite products.
Designer of various scales - Stochastic
Stochastic provides direct and inverse stochastic simulation capabilities. The direct stochastic simulation process calculates a probability distribution function for macroscale amounts of interest, given the variability of microscale geometry and constitutive properties. The inverse stochastic simulation process reverses the probability distribution function of the constitutive properties of the microscale based on the variability of the experimental data at the macroscale (coupon) level. Multiscale Designer - Stochastic provides the data for calculating permissions allowed in bases A and B through a virtual permission supported by the test methodology.
Multiscale Designer - Fatigue
Fatigue is based on the asynotic homogenization approach at two scales in time and on the homogenization of reduced order in space, which can be effectively applied to any architecture of materials and equations constitutive of microphases. Multiscale Designer - Fatigue has been validated for ceramic composites with chemical vapor infiltrate (CVI), fusion infiltrate (MI) and carbon fiber composites reinforced with PMR-15 and MVK-14.
Designer Multiescala - Multifísica
Multiphysics is based on the mechanodiffusion reaction and reaction model at multiple scales coupled unified environmental degradation of polymer composites and ceramic matrices. Multiscale Designer - Mulitphysics engages multiple physical processes at various scales, including oxygen diffusion and/or moisture, reaction and deformation. The striking feature of Multiscale Designer - Multiphysics is its computational efficiency obtained through model reduction for various physical processes. Multiscale Designer - Multiphysics has been validated for PMR-15 and MVK-14 reinforced carbon fiber composite material systems and Melt Infiltrated CMC-NASA N24A materials.
