Description
Simulation study of tensile fracture behavior of unidirectional elastic fiber/elastic matrix composite with weak interface was carried out by means of a Monte Carlo method combined with a modified shear lag analysis. With the present method, following features of weakly bonded composites could be expressed. (1) When the fracture strain of matrix is low, the residual stresses (tensile and compressive stresses along fiber axis for matrix and fiber, respectively) enhances fracture of matrix and interfacial debonding during cooling and/or at low applied strains. As a result, the strength of composite is practically given by the strength of the fiber bundle. (2) When the fracture strain of the matrix and frictional shear stress at the debonded interface increases and the residual stresses decrease, the strength of composite increases. (3) Longitudinal cracks arise at the notch tip and grows to the grip-ends. Therefore, the nocthed strength is given by the net stress criterion.
