I recently posted a C code for the solution of Eshelby problem based on the paper by Jaswon and Bhargava.

In the last couple of days, I learnt that Jaswon also worked with Cottrell on solute drag and is one of the pioneers of boundary element method. The following paper by Martin gives a nice introduction to Jaswon and his work -- along with a complete listing of Jaswon's papers. There is also a lovely photograph of Jaswon with R D Bhargava in the paper and the first few references are also a good place for those who want to understand the history of boundary element method.

We are looking for applicants with Masters or PhD degrees with expertise in C programming (parallel programming skills are preferred but not essential), numerical solutions of partial differential equations (finite difference / Fourier spectral tehcniques are preferred) and linux based computers and high performance computing clusters (GPU exposure is preferred but not essential). The positions are for a duration of 21 to 24 months.

This is a C code based on Jaswon and Bhargava for 2-D solution for the Eshelby problem. Please feel free to write to me in case you find any errors. I am sharing this code under GNU GPL license. In order to upload the code, the file extension is given as txt. Once you download the code, remove the .txt and keep only the .c extension. The command

gcc JaswonBhargava.c -lm

will compile and give you the executable to run.

Adhesion and, its interplay with friction, is central in several engineering applications involving soft contacts. Recently, there has been an incredible push towards a better understanding on how the apparent contact area evolves when a shear load is applied to an adhesive soft contact, both experimentally and theoretically. Although soft materials are well-known to exhibit rate-dependent properties, there is still a lack of understanding in how the loading rate could affect the contact area shrinking.
