Overview

Impacts can range from the most ordinary at low velocity--a tool dropped on a product--to the hypervelocity impact of space debris on a spacecraft. Much research is being conducted on impact on composite structures because significant damage can occur and yet be undetectable by visual inspection.This book explains how damage develops during impact, the effect of impact-induced damage on the mechanical behavior of structures, and methods of damage prediction and detection. Numerous examples illustrate these topics.
