A new quadrature algorithm consisting of volume and integral domain corrections for two-dimensional peridynamic models

Peridynamic (PD) models using the equation of motion in the integral form are applied to describe the failure and damage of materials. At present, the most commonly used volume correction algorithms (VCAs) cannot accurately calculate the volume of the intersecting region between a PD point and its neighbouring cells, particularly for the non-uniform discrete regions, which decreases the accuracy of the PD models. In this study, a new precise VCA...
