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:...

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...

Assessing VABS against ABAQUS Beam Section Generate

27 May 2015 | Teaching Materials | Contributor(s): Su Tian, Wenbin Yu

We did a case study for a composite beam using VABS and ABAQUS beam section generate capability and compared with detailed 3D FEA analysis. The conclusion is that VABS can reproduce the detailed 3D FEA analysis at an efficiency much faster than ABAQUS beam capability. The accuracy of ABAQUS beam...
