The following stress-strain curves were obtained for dif- ferent materials subjecting the specimen to the loading path(a, b, c, d ). Which one(s) of them correspond to elas- tic material(s)

Which of the following expressions represents the rate of work done by the stresses during the deformation of a body of an arbitrary material?

Which of the following expressions most ac curately and simply represents the comple mentary strain energy density Uc of a linear elastic material?

Extend definition to material bodies: total work is the addition of the work done on all particles by forces distributed over the volume W by forces distributed over the surface t·udS

Concept Question Consider the following simple displacement field

Principle of Virtual Displacements Consider a body in equilibrium. We know that the stress field must satisfy the differential equations of equilibrium. Multiply the differential equations of equilibrium by an \arbitrary\displacement field T
