Research Positions at Soft Matter, Interfaces and Energy Laboratory (SMIEL) at UMD in simulations
The Mechanics and Computation Group (Department of Mechanical Engineering) at Stanford University is seeking applicants for the “Stephen Timoshenko Distinguished Postdoctoral Fellowship.” This appointment is for a term of two years, beginning in September 2018.
I am studying the effective material property of a double-layered perforation (Fig. 1). The perforation rate is different on the two layers, which are connected via arrays of pillars. Both perforation and pillars are closer packed in y-direction (the beam length direction) than the x-direction (the beam width direction) to render an anisotropic in plane material property. Fig. 1 (b) shows a unit cell of such a periodic perforation.
I am studying the vibrational behaviour of a microbeam made of a polymer (Fig. 1). The beam consists of a paddle part and a tapered part and is fixed at the tapered end.

The compressive mechanical responses of silicon nanoparticles with respect to crystallographic orientations are investigated by atomistic simulations. Superelastic and abrupt hardening-stiffening behaviors are revealed in [110]-, [111]- and [112]-oriented nanoparticles. The obtained hardness values of these particles are in good agreement with the experimental results. In particular, [111]-oriented particle is extremely hard since its hardness (∼33.7 GPa) is almost three times greater than that of the bulk silicon (∼12 GPa).
Professor Huajian Gao of Brown University speaks at MIT Distinguished Seminar Series (March 2016).
It is a unique opportunity to enjoy the many important recent achievements of Huajian's group.

Dear colleagues and friends,
On the occasion of the 13th World Congress on Computational Mechanics (WCCM 2018, http://www.wccm2018.org) to be held in New York City on July 22-27, 2018, we are organizing the mini symposium
Concurrent multiscale modeling in solids and structures: coupling methods from micro to macro scales (MS 411).
G'day all
Having a metal element with a notch like crack (assume sharp one, exhibits plasticity), what are the actual fracture mechanism (the phases the crack goes through) in the total fatigue-life.
please comment on these scenarios:
1- crack initiation life calculated from the (S-N, e-N), then using LEFM/EPFM to determine the cycles for the crack propagation to failure...
Q/ how to find the crack length between the two phases, I mean from which stresses and at which crack length we start the crack propagation life estimation.
