ANALYSIS OF THE STRESS-STRAIN STATE OF SPHERICAL SHELLS WITH THE HELP OF THREE-DIMENSIONAL ELEMENTS

Cover Page

Abstract


Approach of modeling of massive and thin-walled elements of designs of the difficult geometry which has been set in spherical coordinates by three-dimensional final elements is developed. The three-dimensional object is set by parameters of a single cube which breaks into final elements. The decision in an element is submitted in the form of an interpolation hermit cubic spline of three variables. The analysis intense the deformed condition of a thin- walled spherical cover with local deepening is made.
