Notes:
A three-dimensional damage percolation model, which captures the effect ofmicrostructural heterogeneity on damage evolution, has been developed to model damage initiationand propagation in materials containing second phase particles. It considers the three phenomenapreceding ductile rupture of the material: void nucleation, growth, and coalescence. ThreedimensionalX-ray tomography is used to obtain measured three-dimensional second phase particledistributions in aluminum alloy sheet. Material damage evolution is studied within a tensile testsimulation and compared to measured damage from an in situ tensile test utilizing X-raytomography. Experimental and simulation results for material damage initiation and evolution are ingood agreement
