Abstract

Mechanical behavior of hollow ceramic spheres was evaluated using finite element analysis. Failure mode and strength of spheres were determined from stress analysis. A parametric study of strength as a function of wall thickness to sphere diameter ratios indicated that strength is a function of relative density squared. Strength of aluminium oxide hollow spheres made by the coaxial nozzle powder process agreed well with the finite element parametric model.
