EVP deformation, rotating shell, shock waves

Rotating shell dynamic EVP deformation equations with viscoplastic terms considering ni dynamic deformation equations S. P. Timoshenko’s type are built be introducing of viscoplastic deformation speed on perturbation front and transition to local derivative according to the traveled distance instead partial derivative with respect on time. EVP material rotating axisymmetric shell dynamic displacement field near shock waves is built be ray method.Pertrubation fronts velocity movement are identified, two isolated surfaces are shown, each of which reserves their own set of longitudinal and transverse components of perturbation. Weak discontinuity transition two equation systems are obtained, which built on moving surfaces. There are algebraic and differential equations in each of this systems. There are for the longitudinal velocity discontinuity surface algebraic and first order linear heterogeneous differential equations with constant coefficients of the unknown functions. There are for the second transverse velocity discontinuity surface generalized Rikkati equation with variable coefficients, linear heterogeneous differential equations. Longitudinal, transverse and rotation angle mindsection as Taylor’s power row in the surrounding of perturbation surfaces with third order accuracy with material plastic deformation for downloading waves considering solution is presented. Residual irreversible viscoplastic deformation distribution is built after shock waves passing as Taylor’s power row with third order accuracy
