J. F. LABUZ~ J. M. BRIDELL~ INTRODUCTION A basic assumption in material testing is the existence of a uniform stress state, where the loading surfaces are usually the principal planes. During compressive load- ing, however, this condition becomes untenable because a frictional constraint develops at the interface between the material and loading system [1-4]. A cylindrical geometry, for example, takes on a barrel shape and a nonuniform stress state develops throughout the cylin- der. This is esp...
