Constitutive modeling for time- and temperature-dependent behavior of composites

08 Jan 2020

Structural integrity, durability, and thermal stability represent critical areas for adequately modeling the behavior of composite materials. Polymeric matrices are prone to have time-dependent behavior very sensitive to changes in temperature that influence the effective properties of the...

MSC.Patran/Nastran-SwiftComp GUI

01 Apr 2019

A graphical user interface (GUI) has been developed to integrate SwiftComp into MSC.Patran/Nastran for constitutive modeling and providing the automated conversion of the MSG plate and beam stiffness matrix into MSC.Nastran shell and beam element properties and materials. In order to reduce...

VUMAT of a Generalized Standard Continuum Damage Model

13 Apr 2018 | Downloads

Based on a recently developed generalized standard continuum damage model (CDM), this VUMAT user subroutine provides a rigorous and robust framework for implementing various damage behavior into 2D or 3D solid elements in a finite element analysis (FEA). It is designed to be used with...

Woven fabrics UMAT- a coupled material model

02 Aug 2017 | Downloads

One of the advantages of woven fabrics over unidirectional prepregs is their superior formability thanks to the large shear deformation capability. There exists, however, a limit on the shear deformation of woven fabrics, namely the wrinkling. Applying tension to delay wrinkling during forming...
