Development of a quasi-static simulation methodology for a damage tolerance assessment of impact damage in bonded CFRP structures

The concept of lightweight design is driving future aircraft to exploit all the available strength of materials and further reduce the weight of an aircraft leading to lower fuel consumption and more sustainable aviation. Current designs introduce rivets and bolts to join the structure and simultaneously create holes in the pristine material,...

Finite Element Model For Interfaces In Compatibilized Polymer Blends: A Comparative Study on the Mixed-Mode Response of Cohesive Zone Models Implemented With Small and Large Displacement Assumptions

Designing and modeling compatibilized polymer blends require accurate interface model. In addition, it is possible that crazing occurs during failure of the interfaces leading to large deformation prior to complete failure and therefore must be accounted for by the interface model.<br/><br/>A preliminary literature review showed that existing...
