Extreme Environment Damage Index and Accumulation Model for CMC Laminate Fatigue Life Prediction, Phase II

Completed Technology Project

Project Introduction

Extreme Environment Damage Index and Accumulation Model for CMC Laminate Fatigue Life Prediction, Phase II
Materials Research & Design (MR&D) is proposing in the SBIR Phase II an effort to develop a tool for predicting the fatigue life of C/SiC composite laminates, which incorporates mechanical loading at any minimum stress to maximum stress ratio (i.e., R value), at room and elevated temperatures, in either inert or oxidizing environments. The success of this effort would represent a significant state-of-the-art improvement in fatigue projections of ceramic matrix composites, since no tools capable of accomplishing this have ever been developed. The developed algorithm, implemented via user-defined subroutines operating within the ABAQUS public domain finite element software, will represent a significant new addition to the suite tools currently available to CMC designers.
