A new PhD position is available immediately in my group in the area of computational atomistic modeling of grain-boundary segregation and plasticity mechanisms in nanocrystalline alloys. Full description available in the attached file.
Dear colleagues,
We would like to draw your attention to the International Workshop on Plasticity, Damage and Fracture of Engineering Materials, which will take place in Ankara, Turkey on 22-23 August 2019. The deadlines for abstract and full paper submissions are April 19 and June 17 2019,respectively.
I hope some of you may find this work interesting. We show, analytically and numerically, that strain gradient plasticity predicts the existence of an inner elastic field adjacent to the crack tip, reminiscent of a dislocation-free zone. The fact that elastic strains dominate plastic strains near the crack tip implies a paradigm-shift with respect to previous crack tip asymptotic studies in plasticity and gradient plasticity, which neglect elastic strains.

I hope some of you may find this work interesting. We show that kinematic hardening effects play a significant role in monotonic/static fracture.

ANSYS, Inc. has an immediate job opening in Houston, TX for Application Engineer. This is a full time position.
The job entails providing advanced technical guidance on various aspects of computational Structural Mechanics to clients in industry.
Are there any papers/documents on one dimensional bar problem with a cohesive zone element formulation? It should be a zero length non-linear spring in this case right? I am more interested in setting up the problem from the virtual work principles rather than a discussion of the results.
Thanks
