Plane Strain
Plane Strain : Also called in-plane strain in contrast to anti-plane strain; used to simplify mathematical analysis of elastic problem, in which displacement depends on only two spatial co-ordinates and its direction lies in the plane of those co-ordinates. Dip-slip displacement that does not vary along strike is an example of plane-strain deformation. Another example is a Rayleigh wave from a line source. See antiplane strain; also Love (1944)
