Cumulative Damage Model for Advanced Composite Materials.
Abstract
The objective of this research program is to develop a cumulative damage model for polymer-based, fiber reinforced composite laminates, To this end, four major damage modes are identified for concentrated study in this program. These include matrix-dominant transverse cracking and interlaminar delamination, fiber microbuckling under compressive stress, and fiber breaking and splitting under axial tension in the fiber direction. Generally, one or more of these damage modes are observed in the process of laminate failure. Analytical studies have been made in the past to describe the mechanics of each of these damage modes under conditions of static loads. The approach taken in this program is to adopt some of the existing mechanistically augmented damage models and extend them to describe the four types of damage modes under conditions of arbitrary cyclic loads.
