VUMAT of a Generalized Standard Continuum Damage Model
13 Apr 2018 | Downloads | Contributor(s): Zhenyuan Gao, Liang Zhang, Wenbin Yu
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...
Variational Asymptotic Modeling of Composite Dimensionally Reducible Structures
09 Nov 2014 | Publications | Contributor(s): Wenbin Yu
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.

The Best 3D Properties of Composite Laminates
14 Nov 2016 | Downloads | Contributor(s): Orzuri Rique Garaizar, Johnathan Goodsell, Wenbin Yu, Byron Pipes
This presentation is given on ASME IMECE 2016 in Phoenix Arizona. Because composite layers are usually very thin (in the order of hundreds of microns), real composites part are usually made of dozens of or even hundreds of layers. It is difficult to provide a layer by layer modeling of...
