  1. Puck Failure Criteria

    31 Jul 2017

    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...

  2. Structure Genome: Fill the Gap between Materials Genome and Structural Analysis

    29 Nov 2014

    A new concept, Structure Genome (SG), is proposed to fill the gap between materials genome and structural analysis. SG acts as the basic building block of the structure connecting materials to structures and the mechanics of SG governs the necessary information to link materials genome and...

  5. Variational Asymptotic Modeling of Composite Dimensionally Reducible Structures

    09 Nov 2014 | Publications

    This is Prof. Yu's PhD dissertation. In this disseration, the variational asymptotic method has be used to provide a systematic, holistic, and rigorous approach to construct efficient yet accurate models for composite beams, plates, and shells.  

  6. 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...

  7. 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...
