As is well known, the formulation of the equations describing a deformable solid is best done in the Lagrangian setting. For magnetized solids, however, one needs to take into account the magnetic field $h$ and the induction field $b$ generated by the body, whose description is usually done in the Eulerian setting.

Hi all,

How to model a pipe which has pores in its internal surface, when the pipe is filled with water and closed at the both ends. Now when the pipe is impacted in the 3 point bending mode water will enter in side the pores and will cause some damping (resist bending).

What is stress? Who has ever seen stress? Is stress a physical quantity?(second section) Let us re-consider an example for metal foam as show n Figures 1(a,b) that show the local flexuosity under cycle compression loading. Previous researchers used the effective elastic moduli theory and the effective stress concept to study this kind of problem. However, who know what are the approximate stresses at any point in the form, say, at the points A, B, A’, B’?
