Impact Response and Dynamic Failure of Composites and Laminate Materials: Strain-rate effect, energy absorption and modelling

Dynamic Response and Failure of Composite Materials

This book gathers the latest advances and innovations in the field of dynamic loads and testing of composite materials and sandwich structures, as presented by international researchers and engineers at the International Symposium on Dynamic Response and Failure of Composite Materials (DRAF), held in Ischia, Italy, on June 21–24, 2022. Contributions include a wide range of topics such as low and high velocity impacts, smart composites, hull slamming, shock and blast, hail and bird impact, damage resistance and tolerance, failure mechanisms, composite structures, delamination and fractures, progressive damage modeling, micromechanics, ballistic impacts, ceramic and CMC, auxetic materials and structures, additive manufacturing, crashworthiness, green composites, and structural health monitoring.

Impact Response and Dynamic Failure of Composites and Laminate Materials

In many engineering applications of composite and laminate materials, damage and failure can be caused by impact of various types. Low-velocity impact is potentially dangerous because it can produce extensive sub-surface delamination that may not be visible on the surface. High-velocity impact produced by projectiles, shock waves and fragments from exploding ammunition is a highly dynamic event, leading to the penetration or perforation of composites. All impact damage is detrimental to the mechanical and structural performance of composites. Accurate evaluation of the damaged state, and a fundamental understanding of the effect of damage upon the resultant properties are therefore essential for the proper design and application of composite materials. The strain-rate dependence of material behavior, fracture propagation and energy-absorbing capacity are also of paramount importance from both the materials science and structural mechanics perspectives.
