Structure Genome: Fill the Gap between Materials Genome and Structural Analysis
0.0 out of 5 stars
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...

Geometrically Exact Beam Theory (GEBT), is a general-purpose tool for nonlinear analysis of composite slender structures, meeting the design challenges associated with future engineering systems featuring highly-flexible slender structures made of composites. GEBT is based on the mixed...
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
05 Jun 2014 | Teaching Materials | Contributor(s): Wenbin Yu
This lecture notes used used to teach&nbsp;graduate structural mechanics course at Utah State University. In the notes, we formulated the complete classical beam model (extension/torsion/bending in two directions), which is also called Euler-Bernoulli-Saint beam theory, in three ways:...

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...
