Webmodel is a smeared crack model in the sense that it does not track individual “macro” cracks. Constitutive calculations are performed independently at each integration point of the finite element model. ... gives rise to an open crack and the crack is a damage to the structure, the model assumes that cracking causes damage. WebFeb 23, 2024 · Discrete crack models [12] and smeared crack models [13] are main approaches to simulate crack propagation. ... The nonlocal gradient damage model [21], [22], [23], the thick level set model [24], [25], [26] and the phase-field model(PFM) [27], [28], [29] all belong to the smeared crack model.
