Consider a 10 in x 10 in. square element ABCD that is deformed into a shape drawn in dashed line as shown in the figure below. Let a=0.2 in. and b=0.5 in.
a) Identify the corners of the deformed element and mark them with A′,B′,C′ and D′. The change in the length of BD is ____ in. Use positive if the length increased and negative if it decreased.
b) The normal strain, ϵx, is ____________ in./in.
c) The angle between the new x axis and the new y axis after deformation is _____ rad.
d) The shear strain, γxy, is _____________ rad.
