Statistical theory of defect buildup in composite materials and the scale-factor effect in reliability

  • Published:
Polymer Mechanics Aims and scope

Abstract

A statistical theory of fracture based on the concept of defect buildup is applied to composite materials with a definite fiber orientation. On the premise that the concentration of defects that precede a fracture is sufficiently low, asymptotic distributions of defectiveness are established and asymptotic expressions for the reliability function are derived. It appears feasible to use this theory for predicting the reliability and the scale-factor effect for structures made of oriented composite materials.
