Particle Emission and Charging Effects Induced by Fracture
Abstract
A series of studies involving the physical consequences of deformation and fracture of materials are presented. These measurements include fracto-emission (FE) experiments on model rocket propellent, two studies on properties of ejecta (macroscopic particles) from materials including explosive crystals, fracture induced electrical breakdown, the detection of free charge carriers accompanying fracture in single crystal Si, Fe studies on polymers, adhesives, single crystal and amorphous inorganics, studies of fracture surfaces using scanning tunneling microscopy and atomic force microscopy, and two studies on the interaction of intense uv laser radiation with materials. The appendix presents a review article on fracto-emission from interfacial failure. Keywords: Crack propagation; Fracture; Particle emission; Fracto-emission; Energetic materials; RDX; Radiation damage; Electrical breakdown; Microcracking; Laser ablation; Surface charge; Fractrography; Crystal defects; Scanning tunneling microscopy; Atomic force microscopy.
