Three ways to derive the classical plate model

Submitted by Wenbin Yu on

Attached is part of my lecture notes for a graduate structural mechanics. In

the notes, we derived the classical plate theory, which is also called

the Kirchhoff plate theory, in three ways: Newtonian method, variational

method, and variational asymptotic method, using 3D elasticity theory as the

starting point. The self-contradictions of Kirchhoff assumptions and plane-stress assumptions used in both

Newtonian method and variational method are clearly pointed out. The

I am doing one project regarding simulation of modeling residual stress relaxation for AA2024-T351. I am having trouble in introducing cyclic loading for the material. what are the steps needed to do this simulation? i have attached the workpiece dimensions. 

Homogenization technique

Hello all,
 
Why is there no body force considered in the equilibrium equations of the RVE in the homogenization technique?
 
The overall response of the RVE is obtained by solving the RVE boundary value problem under prescribed boundary conditions (either traction or displacement BC) without considering the body force.

Hi

I was modeled a frame @ 6 plates that this plates must be attached to the below frame by some plastic nonlinear translational spring

the specification of this springs ( force-displacement curve) is available & this propety must be define to springs in abaqus model. I can not find this spring in abaqus ,define this propery .hepl me pease to solve this problem.

thanks alot

Scholarships for research exchange in Canada for graduate students of central and south americas

Submitted by Frederick Gosselin on

 The Canadian government offers scholarships ranging between 7500 CDN$ and 10000 CDN$ for graduate students of central/south americas to conduct research internships in Canadian universities. The internships are to last for a duration of 4-6 months.

I am looking for graduate students enrolled in an engineering/scientific program in one of the eligible countries (see below) interested in coming to Polytechnique in Montreal in the next academic year 2012-2013. I have many projects combining fluid and solid mechanics as well as theory and experiments.
