Looking for a job opportunity in Mechanical Engineering

Dear All, 

 My name is Anton and I have graduated from New Mexico State University with my Master's degree in Mechanical Engineering in August. I am currently looking for a job opportunities in both industry and academia (PhD). I am keep looking for an openings on this web-site myself, but I will be grateful for any suggestions. If someone knows any other opportunities please let me know. 

Here is a brief summary of my qualifications: 

•Solid Mechanics and Materials. Physics of Strength and Plasticity. Modeling of Mechanical systems

Abaqus 3d Tunnel model


im making a 3d model of a tunnel excavation and its subsequent settlement using abaqus.

i have made a model in which the tunnel is excavated to a certain section. but my problem is that i cant simulate the progress of excavation. for example a model in which the tunnel gets excavated in 2-meter steps. and in each step 2 meter of soil gets excavated.

i have searched the internet and i think there are plug-ins which can help doing this. can anyone tell me how i can download such plug-ins? or introduce me another way to model the progress of the tunnel excavation?

Modellilng Deep and shallow foundations in Abaqus

Dear All,

I decided to put this post since I am trying to model piles on granular materials with Abaqus and I am having LOADS of problems, some of them due to my lack of understanding in the subject and others becasue there is not enough information around. Some of my problems are:

1- convergence problems: I am using Mohr coulomb for the soil and elasticity for the pile. If the difference between Young's modulus for both materials is to big it does not converge on Abaqus Static. If I do not put a bit of cohesion in my soil it also does not converge.
