Numerical Analytical Method

An axisymmetric problem on determination of the stress state for limited cylindrical shells caused by residual strains is considered. Using of suggested matrizant numerical-analytical method the solution of this problem in refined statement is given. The theoretical model allows taking into account of the effect of transversal shear deformation and the compression of normal. Numerical analysis of the stress state is presented.
