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.
抗滴重冲击 在编号为 2400035 的文章中，Douglas S. Galvao、Chandra S. Tiwary 及其合作者展示了当冲击器（金属尖端）撞击复杂的三维打印多孔结构时，冲击器在整个多孔结构中会经历多个应力集中区域；因此，有效应力会集中在孔隙周围，导致局部变形。在撞击器穿透过程中，撞击能量会被层间撕裂、分层、隆起和结构致密化等各种事件吸收。
