Abstract

Sandwich circular panel with foam core indented by flat-end cylindrical indenter was constructed. Collapse mechanisms and influencing factors of sandwich circular panel was determined, and the mass of sandwich circular panel was lightened through theoretical analysis. The theoretical predictions were verified by comparing with results from commercial code ABAQUS. Results indicate that collapse mechanisms map of sandwich circular panels is similar to beam (panel) in a three-point bend besides the regional boundaries. The maximum material utilization rate of each collapse mechanism is located in the boundaries. The maximum material utilization of all Collapse mechanisms is located in the common point which belong to the face yield mode of collapse, the indentation mode of collapse and the mode B for core shear.
