ARBITRARY SHELL ANALYSIS BASED ON FEM IN MIXED FORMULATION WITH THE APPLICATION OF APPROXIMATION OF TENSOR FIELDS

Cover Page

Abstract


The authors present an algorithm of forming the mixed matrix of relation of the forces and the displacements for six face FE with node unknown displacements and stresses. The algorithm is based on the Reissner's functional and theory of elasticity without simplified hypotheses. The method of approximation of vector и tensor fields was used for the representation of the displacements and stresses related with node unknown parameters. The possibility of using the worked out FE was shown for thin
