  1. 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...

  2. 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...

  3. Puck Failure Criteria

    31 Jul 2017 | Downloads

    Composite materials have been established as competitive materials during the last few decades due to their high strength to l ow weight ratio among other advantages and are widely used in many industries. A recent study has found that the industrial usage of composite failure...
