A Peridynamics-Based Micromechanical Modeling Approach for Random Heterogeneous Structural Materials
Publikováno v:
Materials, Vol 13, Iss 6, p 1298 (2020)
This paper presents a peridynamics-based micromechanical analysis framework that can efficiently handle material failure for random heterogeneous structural materials. In contrast to conventional continuum-based approaches, this method can handle dis
