DETERMINATION OF STRESSES IN THE INTERSECTION OF PLANES UNDER PLANE LOADING ON THE BASIS OF THE FEM

Abstract

For the determination of the stress-strain state of plates which are under flat loading, a volume finite element with quadrilateral cross-section and with the nodal unknown displacements and their derivatives is used. For a node on the border junction of the plates at an arbitrary angle α, it is obtained relations between the nodal unknowns of one plate, taken as main one and the plate adjacent to the main plane with angle α. Two cases are considered: a plate of homogeneous material and a plate made of dissimilar materials.
