Staging analysis of multiscale damage-failure transition in a carbon fiber material under static and cyclic loading based on integral characteristics of micro-tomography data
摘要
The paper presents a methodology for comparing the integral structural characteristics of a carbon fiber material (CFM) under static and cyclic loading. The aim is to identify the damage evolution scenario using micro-computed tomography (MCT) data. Bayesian threshold segmentation based on Gaussian mixtures and cluster analysis are applied to detect small and large pores associated with mechanical loads. These findings contribute to a deeper understanding of the CFM composite behavior under loading and facilitate the development of more accurate damage models.
