Drop-Weight Impact Resistance of 3D-Printed Complex Zeolite-Inspired Structures

Abstract

Drop-Weight Impact Resistance

In article number 2400035, Douglas S. Galvao, Chandra S. Tiwary, and co-workers show that as the impactor (metallic tip) hits the complex 3D-printed porous structures, the impactor experiences multiple stress concentration regions throughout the porous structures; as a result, efficient stress concentrates around the pores, causing local deformation. During penetration of the impactor, the impact energy is absorbed in various events such as the tearing of layers, delamination, bulging, and densification of the structure.
