Fatigue Fracture of Self-Recovery Hydrogels

Dear Colleagues,

Here is our recent paper “Fatigue Fracture of Self-Recovery Hydrogels”. To the hydrogel community, this paper distinguishes the fatigue fracture and the self-recovery of a hydrogel. To the mechanics community, we show that, for the first time in hydrogels, the fatigue threshold depends only on the covalent network, but not on the noncovalent interactions that provide dissipation.

Stress is defined as the quantity equal to ... what?

In introducing the very concept of the stress tensor to the beginning student, text-books always present only indirect relations involving the concept. Thus, you have the relations like "traction = (stress-transposed)(unit normal)" (i.e. Cauchy's formula, for uniform stress), or the relations for the coordinate transformations of the stress tensor, or the divergence theorem (for non-uniform stress). These are immediately followed or interspersed with alternative notations, and the rules for using them.

But what you never ever get to see, in text-books or references, is this: a *direct* definition of the stress tensor, i.e. an equation in which there is only the stress tensor on the left hand-side, and some expression involving some *other* quantities on right hand-side. Why? What possibly could be the conceptual and pedagogical advantages of giving a direct definition of this kind, and its physical meaning? I would like to ponder on these matters here, giving my answers to these and similar questions in the process.

Open Post-doc position at Energy- Control and optimization lab

Energy, Control and Optimization (ECO) lab in the Department of Mechanical Engineering at Texas A&M University has one post-doc position. The research project is about energy conversion in Nano-materials and thin film solar cells. Candidates should have a strong background and interests in Radiative Heat Transfer, Nano-Materials, Nanofabrication, Computational Methods and Machine Learning. Programming experience in MATLAB or Python is necessary.

Using LEFM for analyzing crack in a non linear material

Dear all,

I am trying to find the crack tip SIF in Polyurethane which an elastomer. It behaves like a nonlinear elastic material with the initial small linear elastic region. Can I use a multi-parameter stress field equation (William's crack tip stress field equation) to get the SIF of the crack tip.

Thank you

Advancing the frontiers of silk fibroin protein-based materials for futuristic electronics and clinical wound-healing (Invited review) The present review will introduce the basic concepts of silk-based electronics/optoelectronics including the latest technological advances on the use of silk fibroin in combination with other functional components, with an emphasis on improving the performance of next-generation silk-based materials. It also highlights the patterning of silk fibroin to produce micro/nano-scale features, as well as the functionalization of silk fibroin to impart antimicrobial (i.e. antibacterial) properties.
