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

Stress Tensor
definition of stress

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.

Using LEFM for analyzing crack in a non linear material

Submitted by vivekiitm8 on
research
linear elastic fracture mechanics

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
