CMAS 3.0 Release Information

CMAS 3.0 has been released in April 2011.
In this version, a new material constitutive law of anisotropic viscoelasticity has been added to the non-linear version.

CMAS 3.0: Release Highlights

Non-linear version: Homogenization Analysis (physical properties identified) with viscoelasticity

A material constitutive law of anisotropic viscoelasticity has been added. Accordingly, the scope of the multi-scale analysis has been expanded to include rubber composites, metal matrix composite materials as well as composite material which consists of a viscoelastic body such as a resin as a base material.
Analysis Example: Three-point bending test of the reinforced fiber composite materials.
