cohesive zone with curvature


Anyone have experienece of curved cohesive zone model?

I just find people just use straight line cohesive zone geometry model.

Any difference between these two geometries?

Using Nano Scratch Testing For Composite Failure

One of the major concerns for composite material is it’s durability in final form. The size of particles that form the strengthening additive can drastically affect the overall final performance of the composite material. By using the nano scratch testing method the failure of composite material can be compared to identify the most durable formula.

ADINA Electromagnetics

We have recently added the ADINA Electromagnetics module (ADINA-EM) to our wide range of multiphysics offerings. Using this module, the general Maxwell's equations can be effectively solved and the resulting electric and magnetic fields can be coupled to the fluid flow. For details please see:

For an overview of other multiphysics capabilities of ADINA please refer to: 

Rodney Hill died on 2 February 2011

Rodney Hill was born on 11 June 1921.  He was a Reader, then Professor, in The Department of Applied Mathematics and Theoretical Physics (DAMTP), of The University of Cambridge, during the period 1969-1979. He is widely regarded as among the foremost contributors to the foundations of solid mechanics over the second half of the 20th century. He was author of 'The Mathematical Theory of Plasticity' published in 1950.

On proposals

Every year I try to get funding for things that I'm personally interested in but which may not have any immediate economic benefits.  A couple of years ago, after reading Penrose's "Road to Reality", I thought about applying Clifford algebra ideas to fracture mechanics and wrote up a proposal to that effect.  The proposal wasn't funded, but I think the idea is worth exploring.

The summary of the proposal was

What would you like for an undergraduate book on QM to explain to you?


1. Background:

A couple of things concerning books happened recently, in the last week or two.

(i) Dr. Biswajit Banerjee announced last week that a new book on metamaterials and waves in composites authored by him is coming out in print within a few months.
