Finite element method in application to plane stress problems Mahapatra, Bijaya Chandra
Framework cells and no-bar cells are used for solving plane stress problems by the Finite Element Method of Analysis and the results obtained by using the two types of cells are compared with the elasticity solution in two specific examples. The precision of the Finite Element Method is tested at different values of the Poisson's ratio of the material. The stresses found by the Finite Element Method are calculated in two ways: from the corner forces and the corner displacements, and the quality of the results employing the methods is compared. The precision of the results obtained with the bar cells has been found consistently better than with the no-bar cells. Comparable precision has been observed in the stresses found from the corner forces and the corner displacements.
