Abstract: An improved formula considering the change in densification strain is derived to predict the quasi-static crushing stress of gradient foam material. Besides, a two-displacement field is proposed to describe the deformation of negative gradient foam… read more here.

Abstract: Abstract Wrinkling is a common failure mode of sandwich panels under in-plane compression. The classic methods often underestimate the wrinkling stress, especially for sandwich panels with low-relative-density foam cores. Hence, an accurate method for predicting… read more here.

DOI: 10.1177/1099636217708741
Abstract: Full thermoplastic composite sandwich structures with a foam core offer the possibility to be manufactured by fusion bonding in significant shorter cycle times than thermoset-based sandwiches. However, the application of foam cores results in lower… read more here.
