Designing for impact resistance with unidirectional fiber composites

Energy-absorbing mechanisms are identified and evaluated using several approaches. The energy-absorbing mechanisms considered are those in unidirectional composite beams subjected to impact. The approaches used include mechanistic models, statistical models, transient finite-element analysis, and simple beam theory. Predicted results are correlated with experimental data from Charpy impact tests. The environmental effects on impact resistance are also evaluated. Working definitions for energy-absorbing and energy-releasing mechanisms are proposed and a dynamic fracture progression is outlined. Possible generalizations to angleplied laminates are described.
