  • Damage initiation in composites containing plate-like particles
    Petr, Martin ...
    The modelling of matrix composites damage is an important topic in material science. A dispersion hardened binary Al-Si composite has been chosen for crack initiation modelling. Coarse brittle ... embedded in ductile Al matrix are expected to act as sites of damage initiation .The kinetics of damage at room temperatute is studied as a function of particle characteristics (size and shape).Particle shape is approximated by an oblate regular prism. Measuring single planar sections by an image analyser and using the numerical unfolding procedure we obtain the obtain the bivariate size and shape distribution for both cracked and all particles.A correction factor is used to account for the probability of a crack existing in a particle to be detected in the plane of measurement.The probability of particle damage depending on real three-dimensional parameters is estimated.This enables better understanding ofthe damage initiation process.
