Ductile fracture of controlled microstructures
Abstract eng: The aim of this work is to develop a framework to engineer crack paths by controlling the distribution of second phase particles in a manner so as to increase the materials ductile crack growth resistance. We carry out analyses of ductile crack growth with voids nucleating from discretely modeled particles so as to introduce a characteristic length. Crack growth resistance curves and fracture surface roughness measures are computed for various distributions. The results indicate that by suitably designing the particle distribution, a material’s ductile crack growth resistance can be significantly increased.
