Question about the cohesive element in ABAQUS
I'm a new user for Abaqus. I use the cohesive element of Abaqus to model interface fracture. But i don't know how to determine if the interface failure is mode I or mode II. If you have worked on cohesive elements, and know how to do this, could you please help?
Analytical solution for deflection of plate
I am a third yr undergraduate student of Aerospace Engineering department, IIT Kharagpur. I have a very simple question in strucutral mechanics. Is there any analytical solution available for deflection of plate under distributed load? The governing equation is well known and has been attached as an image file. Only classical plate theory can be considered. The boundary conditions can be taken as classical boundary conditions. So that can be any combination of a) hinged b) clamped and c) free boundary conditions.
Podosomes are dynamic mechanosensors
We recently find that podosomes, very dynamic, self-organized structures, can function as mechanosensors. For details, see the recent issue of Current Biology.

Postdoctoral Appointee – Computational Plasticity
A postdoctoral position at Sandia National Labs in Livermore, CA is available for an applied mechanics engineer with a strong background in computational constitutive model development. The work will support our current projects in the areas of continuum plasticity and failure modeling. The applicant will also be expected to implement models into Sandia computer codes for high-performance computing simulations. In addition, the candidate will collaborate with structural analysts to apply these advanced models to Sandia applications.
Watch the metallic glass "flowing" at room temperature
Metallic glass in bulk form is known to have superb strength and elastic response but very limited plastic deformation ability. Through machining the metaillinc glass into submicometer pillars, experiment found that metallic glass can actually sustain very large plastic doformation (see attached Figure). The detail of this finding can be found in our most recent publication: Z. W. Shan et al, Plastic flow and failure resistance of metallic glass: Insight from in situ compression of nanopillars, Phys. Rev.
