Abstract
This paper presents a micromechanical Finite Element (FE) model to study mode I transverse intralaminar damage propagation in unidirectional (UD) composite materials. A computational framework consisting of Single Edge Notch Tension (SENT) virtual specimens, composed of Unit Cells (UCs) embedded in homogenised regions, is proposed. Random fibre distributions and appropriate constitutive models are used to model the different dissipative phenomena that occur at crack initiation and propagation. The corresponding crack-resistance curve (R-curve) is obtained by fitting the size effect law (SEL) to the peak loads obtained from geometrically scaled SENT FE models.
