Questions related to Continuum Mechanics
To develop constitutive models in continuum mechanics, one must consider kinematics, balance of momentum, balance of energy, and free-energy imbalance. Next, one must propose constitutive response...

In the literature of continuum mechanics, this book sometimes is called "the Monster". some others call it (and the Non-classical field theories by Treusdell and Noll) "the bibles of continuum...

In the couple stress theory we have only dependent macrorotation and we can calculate curvature tensor. But in the micropolar theory we have independent microrotation and maybe macrorotation, but...

suppose there are two material points, before deformation, they have coordinates (x) and (x+dx), the initial distance between these neighboring points are: dS2=dx2 why do we need the distance to...

As we all know, small strain theory is very important in continuum mechanics. It helps linearize the strain tensor as the second-order terms are neglected. Most of the contexts I found read: the...
