Abstract

A modification of three-dimensional finite element in the form of a tetrahedron for calculating three-dimensional structures is considered. We derive a stiffness matrix for a finite element in the form of a tetrahedron with three degrees of freedom at the node. A model of the problem of determining stress-strain state thick cylindrical shells is developed.

Keywords: shell; anisotropy; orthotropy; stress-strain state; different resistance; finite element
