Strains Determination at the Joints of Cylindrical Glass-Metal Composite Shell Layers

Abstract:

The analytical method of residual strains determination on joints of layers of a glass-metal cylindrical shell arising in the course of its cooling description is provided in article. For the numerical implementation of the proposed model modern numerical and digital-analytical methods were used. In connection with the exponential change of the required functions close to butt ends of the shell numerical methods lead to instability of calculation. In order to overcome this obstacle, Godunov’s method of discrete orthogonalization was applied. It has significantly leveled disturbance peaks of strains on the surfaces conjunction of the composite shell layers.
