  1. 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...

  2. Composite Stiffness Property Prediction

    0.0 out of 5 stars 

    07 Aug 2017 | Downloads

    Micromechanical models for the composite axial tensile, transverse tensile, and axial shear are combined into one tool with the objective of comparing their effectiveness as property prediction methods.  Rule of mixtures models (ROM) and the composite cylinder model (CCM) results for...

  3. 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...
