Local inertial effects in dynamic fragmentation

摘要: A general definition of dynamic fragmentation can encompass any impulsive process which partitions a body material into discrete domains. Two examples are due to brittle fracture under impact loading and shear banding in shock‐compression plastic deformation. In application, prediction fragment size or band spacing is frequently either the objective, else requisite understanding process. An approach presented whereby surface interface area created governed by an equilibrium balance energy local inertial kinetic energy. Fragment be approximately related area. Relations provided analysis compare well with experimental shock‐wave shear‐band results.
