This video is an introduction to stress and strain, which are fundamental concepts that are used to describe how an object ...

A fixed-free rod is heated uniformly by an amount of ΔT. The rod experiences axial and transverse strains due to temperature increase; however, no stress is developed since the right end of the rod is ...

If the Poisson's ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

Well, it’s more common than you think. Job stress is robbing U.S. workers of the sleep they need, researchers reported in a ...

This paper closes by discussing the possible conditions under which members of support systems may transfer or exacerbate stress effects rather than alleviate them. En este articulo, el modelo Demanda ...
