  5. VUMAT of a Generalized Standard Continuum Damage Model

    0.0 out of 5 stars 

    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...

  6. Woven fabrics UMAT- a coupled material model

    0.0 out of 5 stars 

    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...
