Discrete Damage Mechanics
Discrete Damage Mechanics (DDM) calculates the crack density, i.e., number of cracks per unit length, in every lamina of a laminate when subjected to any loading. The only material properties needed ate the intralaminar fracture energy in mode I and II. In most cases, only mode I is needed. The following articles describe the model: - Cortes, D.
