Abstract

The paper discusses the concepts of equal strength and equal stress structures. We will call equal strength structure, if at each point the equivalent stress corresponding to a particular theory of strength is equal to the ultimate strength of the material. In equal stress structure at all points of the body the stress state is the same. Considering that in inhomogeneous bodies ultimate strength may be variable equal strength and equal stress structures are different concepts. On the basis of the inverse problem of elasticity theory of inhomogeneous bodies and strength criteria for the concrete is considered the method of constructing the model equal strength thick-walled concrete cylinder. In practice, the creation of a concrete cylinder with continuous inhomogeneity is quite difficult. Therefore, there is proposed a method of creating a piecewise inhomogeneous structures are close to equal strength.
