Structure Genome: Fill the Gap between Materials Genome and Structural Analysis
06 Jan 2015 | Contributor(s): Wenbin Yu
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...

Three ways to derive the classical plate model
19 Jun 2014 | Teaching Materials | Contributor(s): Wenbin Yu
Attached is part of my lecture notes for a graduate structural mechanics. Inthe notes, we derived the classical plate theory, which is also calledthe Kirchhoff plate theory, in three ways: Newtonian method, variationalmethod, and variational asymptotic method, using 3D elasticity theory as...
Three-ways to derive the Euler-Bernoulli-Saint Venant Beam Theory

A Last Paper: An Equivalent Plate Modeling of Corrugated Structures
5.0 out of 5 stars
23 May 2014 | Publications | Contributor(s): Wenbin Yu, Zheng Ye, Victor Berdichevsky
An equivalent classical plate model of corrugated structures is derived using the variational asymptotic method. Starting from a thin shell theory, we carry out an asymptotic analysis of the strain energy in terms of the smallness of a single corrugation with respect to the characteristic length...
