Damage Prediction

Material damage in peridynamics (PD) is introduced through elimination of interactions (micropotentials) among the material points. It is assumed that when the stretch, \( {s_{(k)(j) }} \), between two material points, \( k \) and \( j \), exceeds its critical value, \( {s_c} \), the onset of damage occurs. Damage is reflected in the equations of motion by removing the force density vectors between the material points in an irreversible manner. As a result, the load is redistributed among the material points in the body, leading to progressive damage growth in an autonomous fashion.
