Abstract

Micro-damage development from notches in composite laminates can be the limiting factor in the use of those materials in engineering structures. The present paper presents some of the results of an extensive study of that process, and specifically addresses three aspects of the problem, the local mechanics associated with the damage development sequence, global changes in the stress state near the notch that relax the stress concentration, and the mechanics associated with the remaining strength after damage has occurred. Such things as material constituent properties and laminate stacking sequence may control which features dominate the resulting response, especially the remaining strength and life. Contrasting cases will be discussed and analyzed. Several modeling approaches will be suggested.
