Plane Strain Plane strain is defined to be a state of strain in which the strain normal to the x-y plane zand the shear strains xz and yz are assumed to be zero. The assumptions of plane strain are realistic for long bodies (say, in thez direction) with constant cross-sectional area Continuous, large strain, tension/compression testing of Dec 01, 2005 · Unfortunately, large-strain, in-plane compression is difficult to attain in sheet materials because of buckling modes that develop. Compression testing of sheet material generally takes one of two forms. The first approach emulates the geometry of the bulk compression test, which has a length-to-diameter ratio of 3 (ASTM E9-89a, 2000).

Stress and Strain Geology

When stress causes a material to change shape, it has undergone strain ordeformation. Deformed rocks are common in geologically active areas. A rocks response to stress depends on the rock type, the surrounding temperature, and pressure conditions the rock is under, the length of time the rock is under stress, and the type of stress.
