On the anisotropy of adhesively bonded metallic hollow sphere structures

This paper addresses the mechanical properties of adhesively bonded metallic hollow sphere structures (MHSS). Finite element analyses are conducted in order to determine Young’s modulus and the initial yield stress dependence on the loading direction. Therefore, three dimensional unit cell models with a primitive cubic arrangement of hollow spheres are analysed. Within the numerical analyses, two different morphologies, namely syntactic MHSS and partially-bonded MHSS, are considered.
