Response of composite sandwich panels with transversely flexible core to low-velocity transverse impact: A new dynamic model
TLDR
In this paper, a new computational procedure based on improved higher order sandwich plate theory (IHSAPT) and two models representing contact behavior between the impactor and the panel are adopted to study the low velocity impact phenomenon of sandwich panels comprising of a transversely flexible core and laminated composite face-sheets.About:

A model to predict low-velocity impact response and damage in sandwich composites
TL;DR: In this paper, a modified energy-balance model coupled with the law of conservation of momentum is proposed to extend the validity of elastic impact models beyond the elastic regime, and three parameters were derived from the static load-deformation response: the elastic stiffness, the critical load at the onset of damage, and the damaged stiffness.

Effect of impactor shapes on the low velocity impact damage of sandwich composite plate: Experimental study and modelling
TL;DR: In this article, an experimental and numerical analysis of the influence of impactor shapes on the low velocity impact performance of aluminium sandwich composite plates has been carried out, where the composite panels were manufactured by using two aluminium sheets and a low density polyethylene core under heat and pressure, which shows the outstanding properties of low weight, good rigidity and impact resistance.

High‐Order Theory for Sandwich‐Beam Behavior with Transversely Flexible Core
TL;DR: In this paper, a general high-order theory based on variational principles is presented for the bending behavior of a sandwich beam with a core that is vertically flexible, which embodies a rigorous and systematic approach to the analysis of such structures, which have highorder effects caused by the nonlinearity of the longitudinal and the transverse deformations of the core through the height.
