Abstract

An experimental and numerical study of in-plane compression of foam core sandwich columns with implanted trough width face/core debond is presented. Experiments were conducted for columns with two different face thicknesses over different cores and debond lengths. The debonded region was monitored using digital image correlation (DIC) measurements. Finite element analysis and linear elastic fracture mechanics are employed to predict the residual compressive strength of columns. Finally, the numerical results are validated with column testing. Results show a good agreement between finite element and experimental results.
