摘要: Abstract The objective of this paper is to predict the entire stress/ strain curves and loss stiffness with damage for sheet-moulding-compound (SMC) composites. This achieved by developing a statistical micro-macro relationship help model Mori Tanaka. In case an SMC composite 32% fiber volume fraction, debonding at fiber/matrix interfaces predominant ‘microdamage’ mechanism. order relate microstructure, its local perturbations, macroscopic damaged behaviour, we introduce criterion concept equivalent inclusion in shows between interface failure scattering observed on mechanical test results.
