Structure Genome: Fill the Gap between Materials Genome and Structural Analysis
06 Jan 2015
This presentation is given at 2015 AIAA SciTech conference. 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...

SwiftComp: Right Results Right Away
13 May 2015
This presentation gives a brief review of SwiftComp which is a general-purpose multiscale constitutive modeling code. It can bridge microstructure with the final macroscopic structural model. It takes a FE mesh of Structure Genome, which is defined as the smallest mathematical building block of...

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...
