I am Luo Li and I am a graduate student from UNM. I am currently working with Dr.Tariq Khraishi. We published a paper 'The Strain/Stress Fields of a Subsurface Rectangular Dislocation Loop Parallel to the Surface of a Half Medium: Analytical Solution with Verification' in Jamp. Now, we are wokring on the paper 'Stress Field of a Rectangular Dislocation Loop'. I hope I can investigate more problems in the future.

Stress Field of a Rectangular Dislocation Loop Luo Li , Tariq Khriashi Abstract The stress field of a rectangular dislocation loop in an isotropic solid in an infinite medium is obtained here for a Volterra-type dislocation. Explicitly, the stress field of the dislocation loop is developed by integrating the Peach-Koehler equation over a finite rectangular dislocation loop. In this paper, numerical verification of the stress field is demonstrated (for the Equilibrium Equations and Strain Compatibility Equations).
