When the plate is subjected to a state of homogeneous deformation ( same strain at all points of the plate ) the plate becomes a parallelogram and the opposite sides remain parallel, but the

Unformatted text preview: internal angles might be different from the original π /2. Consider the four deformed (dashed) shapes for the plate depicted below. Assume that the deformations are small (small strain, the deformations in the pictures have been magnified for clarity). Give expressions for the in-plane components of the strain tensor: ε xx , ε yy , ε xy , ε yx and for the engineering shear strain γ xy for each case.
