Fracture Mechanics of Advanced Composites (DEPSCoR 92).

Abstract

This report document instrumentation obtained under a DEPSCoR grant to support research in the mechanics of advanced composite materials. While the equipment will support a broad range of research topics, it has already spawned studies into micromechanical fracture of advanced composite materials and nondestructive evaluation of cracked bodies. Specifically, a laser interferometry system (including optical and vibration isolation components with image processing hardware and software), and a tensile substage for an electron microscope, form the core of an experimental program which complements analytical computational investigations. Progress is being made in two particular areas. The first of these is the development of a coupled experimental and computational methodology for solving inverse fracture problems using laser holographic interferometry. The methodology can be utilized in the fracture mechanics of homogeneous and heterogeneous media to determine the location, size and geometry of an embedded crack given the measured displacement history of a free surface.
