Mathematical Construction of a Reissner–Mindlin Plate Theory for Composite Laminates

03 Jun 2015 | Publications | Contributor(s): Wenbin Yu

A Reissner–Mindlin theory for composite laminates without invoking ad hoc kinematic assumptions is constructed using the variational-asymptotic method. Instead of assuming a priori the distribution of three-dimensional displacements in terms of two-dimensional plate displacements as what is...

SwiftComp: Right Results Right Away

13 May 2015 | Online Presentations | Contributor(s): Wenbin Yu

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...

A Critical Assessment of Computer Tools for Calculating Composites Wind Turbine Blade Properties

16 Mar 2015 | Publications | Contributor(s): Wenbin Yu

The purpose of this paper is to critically assess several computer tools for calculating the inertial and structural properties of wind turbine blades. The theoretical foundation of each tool is briefly summarized, and the advantages and disadvantages of each tool are pointed out. Several...
