STUDY ON THE LOW-VELOCITY DYNAMIC RESPONSES OF PRE-STRESSED COMPOSITE PYRAMIDAL LATTICE STRUCTURES
A finite element model is established for the pre-stressed composite pyramidal lattice structures. The influences of prestress on the contact force, contact duration, structural deformation, energy absorption and impact damages are investigated. Before subjected to low-velocity impact,the composite...
