Abstract

This paper investigated the uniaxial mechanicalproperties of a new type of hollowspherestructures. For this new type, the sphere shell was perforated by several holes in order to open the inner sphere volume and surface. The mechanicalproperties, i.e. elastic properties and initial yield stress of perforatedhollowspherestructures (PHSS) in a primitive cubic arrangement were numerically evaluated for different hole diameters and different joining techniques of the hollowspheres. The results are compared to classical configurations without perforation.
