We seek to characterize the local state of deformation of the material in a neighborhood of a point P. Consider two points P and Q in the undeformed

The following expression is the right statement of linear momentum balance for a deforming body of an arbitrary material

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?

Which of the following are real problems with the ritz method 1. Selection of basis functions for general ge- metres 2. Lack of systematic procedure to compute stiff atrix and forcing terms
