Stephen Timoshenko Distinguished Postdoctoral Fellowship at Stanford University
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.
Regarding to the effective elastic tensor form of a double layered perforation panel
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.

Metastable phase transformation and deformation twinning induced hardening-stiffening mechanism in compression of silicon nanoparticles
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).

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.
