WebThe results of the smeared crack model did not match well with the skeleton curves of S110, S220, and S280. In other words, the difference in the rebar spacing cannot be properly accounted for by the smeared crack model. However, by using the discrete crack model, the test results could be well predicted until the peak load. WebOct 1, 2024 · Generally, the damage pattern includes a mix of relatively large matrix cracks, splits, delamination and networks of distributed micro-cracks (Fig. 1). In finite element (FE) analyses of progressive failure of composite laminates, two approaches are possible: discrete crack model (DCM) and smeared crack model (SCM).
