摘要：
The thick-walled sphere under internal pressure is considered. It is supposed that the material of the sphere obeys the linear hardening law. It is shown that stresses for the compressible material can be received from those for the incompressible one by substitution of a shear hardening modulus to some reduced modulus which is larger than the former. Calculations show that neglecting of compressibility can give perceptible error in value of maximum tensile stress.
