Abstract

Hollow sphere structures are lightweight materials and belong to the group of cellular metals (such as metal foams). Metal foams exhibit a several interesting mechanical properties. This contribution investigates the elastic-plastic properties of a new type of hollow sphere structures. For this new type, the sphere shell is perforated by several holes in order to open the inner sphere volume for the matrix material. The effective elastic-plastic properties of syntactic (i.e. spheres embedded in a matrix) perforated sphere structures in a primitive cubic arrangement of unit cell models are numerically evaluated for a different filler fractions of the spheres. The results are compared to configurations without perforation and configurations where hollow spheres are only connected by so called “sintering necksâ€, i.e. not completely embedded in a supporting matrix. In the scope of this study, threedimensional finite element analysis is used in order to investigate unit cell models. The present investigation revealed that sintered arrangement of perforated hollow sphere structure is superior in terms of initial yield stress compared to the syntactic arrangement counterparts. The stronger structure possessed by sintered arrangement model is attributed to network of sphere morphology. The results also indicate a continuous cubic curve of 0.2% offset yield stress for syntactic and sintered arrangement models.
