Effect of surface elasticity on extensional and torsional stiffnesses of isotropic circular nanorods

We present a continuum formulation to obtain simple expressions demonstrating the effects of surface residual stress and surface elastic constants on extensional and torsional stiffnesses of isotropic circular nanorods. Unlike the case of rectangular nanorods, we show that the stiffnesses of circular nanorods also depend on surface residual stress components. This is attributed to non-zero surface curvature inherent in circular nanorods.

Traditional Failure Criteria

Hey every one,

I had a look at the book 'Fracture Mechanics, an introduction' by E.E. Gdoutos, in the preface he talks about "Traditional Failure criteria" and how it's not capable of "adequately" explaining many structural failures and this shortcoming led to the emergence of fracture mechanics theory by Griffith.

But he doesn't really give an acount of what he (Gdoutos) means by "traditional failure criteria".

Could someone please explain me what is the "traditional fracture criteria" as oposed to new criteria introduced by fracture mechanics?

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.

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).

Fracture mechanism in notched metal

Choose a channel featured in the header of iMechanica: 

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.
