An investigation of the stress concentration around a spherical cavity in a cubic medium is conducted by means of the equivalent inclusion method. Cases of uniformly applied tensile, shear, and hydrostatic (spherical) stresses are analysed and examined. Theoretical formulation and computational procedures are described in detail. Numerical results for some representative cubic crystals (niobium, molybdenum, nickel, and copper) are presented for illustration and important features of the ensuing stress concentration are discussed.
