【Abstract】 In order to analyze the reasonable stress modes assumed, this paper analyses some problems of plate, axisymmetric solid,plate in bending and shell,using hybrid stress elements.The effects of different. stress modes on nodal displacements and stress distributions in the element are examined chiefly. The charactors of the "false stresses" and the improvement of the stress distributions in the element are analysed.更多还原
