Facesheet-Core Interface Delamination in Sandwich Panels

Abstract:

The main objective of the present paper is the characterization of the mixed-mode delamination in sandwich plates. To this purpose a mixed-mode delamination failure model is proposed. Then, the failure model is implemented in ANSYS code to calculate the damage propagation parameters. The analysis is based on the Finite Element Method and interface techniques. Within the interface finite element modeling there are calculated the individual components of spring reaction force, relative displacement and energy rate release along the lamination front.
