In this present study, the numerical behaviors for progressive crushing of composite materials and aluminum–metal composite materials are investigated. State of the art shows the importance of progressive crushing in composites as they lead to superior energy absorption characteristics. Since composite and hybrid materials serve a lightweight potential in structural applications, especially in automotive structures. The usage of these materials in energy absorption applications in automotive structures creates the need for their predictability in numerical simulations. Therefore, a methodology using finite element methods has been proposed to predict the numerical behaviors of composite and hybrid materials under crushing loads. A progressive failure material model is used to simulate the crushing response of a GMT structure. The cohesive zone modeling approach is used to predict the adhesive behaviors between metal and composite structures in numerical simulations. Finally, the cohesive modeling approach is combined with a progressive failure material model to predict the crushing behaviors of Hybrid Metal-Composite Structures.
