## Lecture 11 & 12

Buckling delamination, with two slides on 1D vonKarman plates.

## materials of engineering laboratory

In the spring semester of 2002, Dr. Woldesenbet and I gave a hand-on laboratory course: Materials of Engineering Laboratory, to the junior undergraduate students at the Louisiana State University. In this Blog, I am also adding some state-of-the-art techniques for materials laboratory.

## es 246 project:plane strain extrusion- slip line field solution vs.FEM solution

hi Nanshu Lu,

i'm savita jain. i have project some what related to your topic. can i have results of your final coparision of slip line and FEM solutions.please let me know about any progress in your work.

## an interesting puzzle: multiscale mechanics

an interesting puzzle for fun:

Lame’s classical solution for an elastic 2D plate, with a hole of radius a and uniform tensile stress applied at the far field, gives a stress concentration factor (SCF) of two at the edge of the hole. This SCF=2 is independent of the hole radius.

Consider what happened to this concentration factor if the radius a approaches infinitely small. The SCF is independent of a, so it remains equal to two even when the hole disappears.

## Reproducing Kernel Methods

I am working in the field of microfluidics. I wish apply Reproducing Kernel Method to solve flow problems. Can anybody help me to send the paper "Reproducing Kernel Methods ", Wing Kam Liu, Sukky Jun, Yi Fei Zhang, International Journal for Numerical Methods in Fluids, Vol.

1. How random should be the distribution of nodes in element free galerkin method?
2. How can we decide if a given nodal distribution is optimal discretization?  In case we are using movin

## Some write-ups in mechanics

My googling today brought me to this treasure trove of write-ups in mechanics:

This site contains informal (usually rough draft) technical notes and tutorials on topics in mechanics. The sophistication is at the first or second year graduate level. These write-ups include:
