Abstract: Polycarbonate is a polymer which exhibits extreme toughness, a pronounced yield behavior, and the ability to flow extensively prior to fracture. These characteristics coupled with its birefringent ...

Abstract: An initial study of stress waves propagating in a half space due to a point load on the surface has been accomplished by employing dynamic three-dimensional photoelasticity. The central plane ...

Abstract: Using the method of electron beam moiré, a small region at an interface of a [O2 / 90]s glass fiber reinforced plastic composite has been examined during tensile testing. The tensile test ...

Abstract: A new method of fracture analysis is described. Strains recorded by gages in the immediate vicinity of a propagating crack are analyzed. From the analysis, crack tip position, propagation ...

Abstract: Since the pioneering discussion by Irwin, a significant effort has been devoted to determining stress intensity factors (K) using experimental methods. Techniques have been developed to determine ...
