Nonlinear Homogenization Analysis

Creep Curve Fitting

The strain hardening, exponential, and Norton laws are now available as master curves for curve fitting of creep materials, in addition to the time hardening law. We can now also identify the temperature dependent terms.

Granta MI Interface

Corresponding Particle Dispersion Model

The particle dispersion model is now compatible with the data output function for Granta MI.

Numerical Material Testing Using LS-DYNA

Numerical Material Testing with Symmetric Mesh Upgraded to Official Functionality

Numerical material testing analysis with LS-DYNA using a symmetric mesh model has been upgraded from β functionality to full functionality.

Asymmetric Mesh Numerical Material Testing Using LS-DYNA (β Function)

A solver for asymmetric mesh models has been implemented in LS-DYNA’s numerical material testing analysis. However, it will be provided as a β feature.

Specification Improvement

Nonlinear Homogenization Analysis

Elasto-Plastic Curve Fitting

The user-specified adjustment parameter for elasto-plastic curve fitting is no longer required. This allows us to obtain stable curve-fitting results without the need for special know-how. In addition, curve-fitting results can now be compared using the general Mises space stress-strain characteristics instead of the conventional Hill space stress-strain characteristics.

Viscoelastic Curve Fitting

In the previous curve fitting function, the stiffness matrices that make up some Maxwell elements may contain negative values. From this version, it has been modified to take a positive value for the stiffness component where stress relaxation occurs.
