Fracture Testing of Metals and Composites: Tests and Analyses for Failure Problems with Armament Components.

Abstract

Fracture tests have been broadly applied to failure of armament, including failures caused by each of the three general types of fracture--fast fracture, fatigue cracking, and environmentally assisted cracking. This report describes some fracture mechanics tests and related analyses that have been useful to characterize fracture in armament components made from high strength steels and carbon/epoxy laminates. These include J integral fracture toughness, notch fatigue life, and environmentally-assisted cracking tests and analyses for steels and linear elastic fracture toughness tests for laminates. (MM)
