What is Digimat-VA (“Virtual Allowables”)?
- Productive solution to predict virtual allowables for a full test matrix in just few clicks,
- Unique integration of nonlinear multi-scale modeling, progressive failure and finite element analysis technologies,
- Process, material and testing variability modelling,
- Intuitive and easy to use interface.
Digimat-VA combines efficient micromechanical modeling, progressive failure analysis, and non-linear finite element analysis (FEA) in an integrated solution. With Digimat-VA, engineers can compare laminates stiffness and strength virtually before going into the extensive and expensive process of developing physical allowables. They define their test matrix through Digimat-VA’s “point-and-click” interface, and the software generates the virtual allowable based on the test parameters and the ply data.

Case Study
Designing lightweight continuous fiber reinforced plastics (CFRP) structures with confidence requires access to allowables values. Allowables generation is extremely time and money consuming. Various layups, coupon tests and environment conditions must be covered for each characterized material system. Each test configuration must be repeated many times to obtain a statistical evaluation of the mechanical property…
…Virtual allowables can be predicted thanks to advanced multi-scale simulation. By combining mean-field homogenization, progressive failure, non-linear FEA analysis and stochastic methods, allowables become accessible at a fraction of the usual cost and time…
…The comparison with experiment reveals that both mean and B-Basis values are generally predicted within 10 % of error compared to experimental response.
