DAMASK 3 – Computational Materials Science

MULTI MATERIAL

Use multiple materials and constitutive descriptions in a single model.

MULTI FIELD

Fully coupled simulation of mechanics, temperature, and damage.

MULTI SCALE

Simulations from the microstructure scale up to the component scale.

The Concept

DAMASK is a unified multi-physics crystal plasticity simulation package. The solution of continuum mechanical boundary value problems requires a constitutive response that connects deformation and stress at each material point. This problem is solved in DAMASK on the basis of crystal plasticity using a variety of constitutive models and homogenization approaches. However, treating mechanics only is no longer sufficient to study nowadays advanced high strength materials. In these materials deformation comes along with phase transformation, significant sample heating, and damage evolution. Therefore, DAMASK has recently been extended to treat multi-physics problems. Following a modular approach additional field equations are solved in a fully coupled way using a staggered approach.
