Mathematical relations related to the lode parameter for studies of ductility
(2016)
During plastic flow, hydrostatic pressure and plastic strain control the size of the
yield surface while the Lode angle is responsible for its shape. The von Mises
yield condition shows no dependency of the Lode angle ...
On the study of ricochet and penetration in sand, water and gelatin by spheres, 7.62 mm APM2, and 25?mm projectiles
(2016)
We examine the ricochet and penetration behavior in sand, water and gelatin by steel spheres, 7.62 mm APM2 and 25 mm projectiles. A threshold impact angle (critical angle) exists beyond which ricochet cannot occur. The ...
Micro indentation hardness testing of commercial-grade RDX crystals
(2016)
This paper describes the continuous micro indentation hardness testing of two
commercial grades of RDX with differing shock sensitivities using three (3)
different loads on a Berkovich indenter to obtain values of elastic ...
