Study of the influence of the pore manner of aggregation on the crack growth path in a finite element model of a porous alloy
The work presents the results of studying the process of crack origin and development by finite element analysis in models of a single-phase alloy containing micro-sized aligned populations with cubic, asymmetric, and hexagonal isometrical systems. As a result of computer modeling, data were obtained on the nature of the distribution of stresses and strains, and the crack growth path. A comparative analysis of the crack growth path in the models was performed, and it was also confirmed that the pore could serve as a stop on the crack growth path.
