Experimental Investigation of Adiabatic Shear Banding at Different Impact Velocities

Abstract

During the interim period, Nov. 19, 1991 to May 18,1992, the operational stage of the new experimental technique of fast shearing has been achieved. The technique has been tested, as a preliminary stage, on annealed low alloyed mild steel (0.17% C, 0.58% Mn). It was attempted to find the conditions for critical shearing as a function of impact velocity. A scanning electron micrographs of the fracture surfaces have been taken. However, still the open question remains which kind of steel should be tested as a final solution. The Principal Investigator had asked both places, that is MLT-WATERTOWN and ETCA-PARIS-ARCUEIL, about two months ago, and so far suggestions have not came. Finally, one post-doc has been hired to study rate effects in Mode II of fracture.
