Delamination and Fracture Modeling Techniques for Shell Composite Structures in LS-DYNA®

Define numerical analysis capable of predicting the behaviors of laminates composites is a research challenge for engineers and scientists from the first implementation of laminated model for shell elements in 1984 [1]. In these last 35 years all aspects of composite materials behavior have been evaluated such as for example, the impact response, crack propagation, crushing resistance. All contributions, for example from Abrate [2], Farley et al. [3], Botkin et al. [4] to actuals individuated a lot of ways to study numerically all aspects associated to related topic, as descripted and clearly resumed in the following picture.
