How to change the Navier equations for non-uniform Lame's constants

Submitted by habibbaluwala on
research

Hi Everyone,

                 I have to confess here that I do not have a mechanics background but I am currently working on a problem where i have to solve the Navier equation with non-uniform Lame constants of an object. If anyonme could guide me towards the necessary literature or  any other resource it would be very helpful. Sorry for any inconvenience.

A new paper titled "Enabling Ultrahigh Plastic Flow and Work Hardening in Twinned Gold Nanowires " from Dr. Sansoz's group just came out on the latest issue of NanoLetters. Attached below is the abstract and the full paper can be found at: http://pubs.acs.org/doi/abs/10.1021/nl803553b. We welcome any comment about this paper as well as our research.

Chaboche elasto-viscoplastic model with plastic strain memorization and time-recovery in ANSYS

chaboche

Hi, I am a reserach fellow of mechanical engineering in Italy. I need to implement the elasto-viscoplastic model of Chaboche in a user subroutine in ANSYS accounting also for the plastic strain memorization and for the static and dynamic recovery. In a next step I sould also need to incorporate the damage variable of this model.

Phase Field Modelling of Fracture Mechanics

Submitted by PrajwalSabnis on

Hello To one and All,
 

I am currently working on my Master's thesis in Computational Mechanics and as the Title suggests, I am working on using phase field theories to model fracture mechanics. The whole idea /concept of phase field modelling in itself has been a very complex topic for me, as it originates in superconductivity theories of which I have but a superficial understanding. I am ok with fracture mechanics terminology as I have worked on it before.
