Application of Monte Carlo Simulation Method to Tensile Behavior of FRM

The Monte Carlo simulation method was applied to describe the tensile behavior of unidirectional singleand multi-fiber-metal matrix composites. The simulation for single fiber-composites could describe the experimental results of the progress of multiple fracture of fiber with increasing applied stress and the influence of fiber volume fraction on the final average length of broken fiber in the W(fiber)/Cu(matrix). By applying this method to the multiple fracture process, the interfacial shear strengths of the high T c oxides (YBa 2 Cu 3 O x and Ba 2 Sr 3 Ca 2 Cu30 y )/Ag were estimated to be nearly 30 and 40 MPa, respectively. The simulation for multi-fiber composites could describe well the experimentally observed results such as the relation of scatter of strength of the contained fibers to the fracture mode of B/Al, influences of scatter of strength of fibers on the scatter of strength of Nl^Al/Cu composite, the gauge-length-dependence of strength of Nb 3 Al/Cu composite, temperature-dependence of the strength of Si-Ti-C-0 (Tyrrano fiber)/Al composite, and influence of fabrication condition on the fracture morphology and strength of B/Al.
