The analysis of behaviour of multilayered conic shells on the basis of nonclassical models

Summary

The parametrical analysis of stressed-deformed state of multilayered reinforced conic shell on a basis of vectorially linear and nonlinear variants of classical and nonclassical theories is done. The influence of structure of reinforcement of a composite material, the cross shift of binding and the order of arrangement of the reinforced layers on the behaviour of shell are investigated. The comparison of the numerical solutions obtained by the methods of spline collocation and discrete orthogonalization is conducted among themselves and with the numerical results obtained by the method of invariant immersing. High efficiency of the used numerical methods is shown on the example of the solution of boundary-value problem for stiff systems of the differential equations.
