Quasi-static Punch Indentation of a Honeycomb Sandwich Plate: Experiments and Modelling
Punching experiments on wide honeycomb sandwich beams were performed to evaluate the predictive capabilities of a newly developed constitutive model in structural applications. The employed constitutive model for plastically com-pressible orthotropic materials accounts for both non-uniform hardening and softening associated with stressing in different directions. This feature is vital when asse...
متن کاملmodelling of the indentation behaviour of thermoplastic honeycomb sandwich panels
thermoplastic honeycombs based on polypropylene are one of the latest types of cores used in sandwich structures. up to now there have been few experimental and modelling studies on the mechanical behaviour of sandwich structures with thermoplastic cores. in this paper, by considering the similar properties of foams and thermoplastic honeycombs, attempts are made to model the static indentation...
متن کاملInvestigation of Quasi-Static Indentation Response of Inkjet Printed Sandwich Structures under Various Indenter Geometries
The objective of this investigation was to determine the quasi-static indentation response and failure mode in three-dimensional (3D) printed trapezoidal core structures, and to characterize the energy absorbed by the structures. In this work, the trapezoidal sandwich structure was designed in the following two ways. Firstly, the trapezoidal core along with its facesheet was 3D printed as a sin...
متن کاملQuasi-Static Three-Point Bending of Carbon Fiber Sandwich Beams With Square Honeycomb Cores
Sandwich beams comprising identical face sheets and a square honeycomb core were manufactured from carbon fiber composite sheets. Analytical expressions were derived for four competing collapse mechanisms of simply supported and clamped sandwich beams in three-point bending: core shear, face microbuckling, face wrinkling, and indentation. Selected geometries of sandwich beams were tested to ill...
