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 ...

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

The tensile behavior of composites is also different from that of metals in the 'plastic deformation' region of the stress/strain curve. The diagram shows the curve for a uniaxial sample tested along ...

SEVERAL investigators have shown that the behaviour of rubber is affected appreciably by its previous stress-strain history. Their observations, in the main however, are based on indirect ...

Materials in human-powered vehicles are not only subjected to simple tension or compression loads ... deflection measured using an optical lever technique. Torsional stress-strain curves will be ...
