Accurate and Efficient Workflow for Hyperelastic Material Simulations

We are pleased to announce the release of Marc 2018 which improves the efficiency and accuracy of rubber and hyperelastic simulations by introducing a new damage model and extending multiphysics capabilities. The added  can be used to predict potential in-service problems due to material degradation while the new coupled solution allows engineers to simulate the heat generation and hence temperature increase of viscoelastic materials under cyclic loading.

In addition, new automated methods in Marc 2018 make it easier to efficiently create contact definitions for large assemblies and define a large number of springs and preloaded fastener bolts. Marc 2018 also introduces a localized convergence check option that is expected to improve the accuracy and potentially the efficiency of a wide range of simulations.

Key Highlights:

  • Improvements to Seal and Rubber Workflows
    • Calculate the heat generated from high frequency loading of viscoelastic materials
    • New Ogden-Roxbugh damage model for rubbers
  • More Efficient Contact Modeling
    • Automatic generation of contact tables
  • Improved Accuracy and Robust Solution Process via New Convergence Controls
    • Localized options for convergence checks to improve accuracy
  • Advancements in Multi-Physic Simulations
    • Extended support for symmetry across all multi-physics simulations
    • Support of magnetic properties in simulations that involve phase transformations
  • Interoperability with other FEA solvers

Other Enhancements:

  • Improved Mentat Usability
  • Efficient Multiple Spring and Preloaded Fastener modeling
  • Further Extension of Material Data Fitting
