Accurate material modeling is a key to realistic finite element (FE) simulations. Different material models are used for different classes of material, each aiming to capture the correct physical behavior.

A variety of commercial FE software packages are available in the market. Each may have equivalent models that represent the same material behavior. Use of a particular material model may be preferred due to legacy, ease of use, availability of data, and standard practice in a particular industry.

This document provides guidance on developing equivalent material modeling techniques in Abaqus for GISSMO and MAT_ARUP_ADHESIVE models in LS-Dyna. These models are popular in the industry but currently not available in Abaqus. GISSMO model is widely used in the automotive industry for crash simulations. This document describes the GISSMO model and its equivalent modeling approach in Abaqus. The MAT_ARUP_ADHESIVE material model is discussed briefly, only in terms of usage in Abaqus.

Abaqus is a unified finite element analysis (FEA) code, and is a part of the SIMULIA brand of DASSAULT SYSTEMES. SIMULIA also offers simulation products in other technology domains such as fluids, electromagnetics, and so on.

Target audience: FE analysts, LS-Dyna users, Abaqus users, etc.
