The book "Dynamic Failure of Composite and Sandwich Structures" provides a comprehensive overview of the current state of the art regarding the dynamic response of composite and sandwich structures subjected to impacts and explosions. It combines a thorough literature review with original contributions from the authors. The first section addresses the interactions between fluid and structure in maritime applications, focusing on hull slamming, particularly in cases where the deformation of the structure affects the fluid movement during the ingress of water in flexible hulls. Subsequent chapters examine the effects of explosions on these structures, offering rare results from extensive testing. The second section is dedicated to the impacts on laminated composite structures, including ballistic effects and the simulation of dynamic failure. The third section discusses sandwich structures with laminated face sheets and their specific challenges.
