Abstract

A 3D microstructure-based model was developed to study the crack growth in Al/SiCp particle reinforced composites. The complex geometry of the SiC particles in three dimensions was captured using a serial sectioning approach. The model showed that crack deflection due to reinforcement particles makes the crack path tortuous and improves the crack growth resistance of the composite. Serial sectioning process allows the capture of realistic microstructure of particles that includes geometry, orientation, and distribution of the particles. The complex crack growth phenomenon in particle reinforced composites were shown clearly by the model. Incorporation of the explicit microstructure also clearly shows that the crack profile through the SiC particles is captured and the tortuous nature of crack growth and deflection of crack reduces the crack-tip driving the force of the material.
