Dear Mechanicians,

ABAQUS has a number of little-known built-in material models that are not documented in the manuals.

They are accessible from https://www.3ds.com, follow the path "Support", "Knowledge Base" and search for "Built-in user material models for Abaqus/Standard and Abaqus/Explicit". Below is a text version of the output.

It may be that you need special rights on the site; these can be requested from your regional SIMULIA HQ.

See also //m.limpotrade.com/node/18476 for the shape memory alloy model.

Good luck

Frank
