This chapter deals with the static analysis of 2D solids, particularly in plane stress. Plane stress analysis refers to problems where the thickness is quite small when compared to other dimensions in the reference plane x−y. The loads and boundary conditions are applied at the reference or middle plane of the structure. Displacements are computed at the reference plane. The stresses related with z coordinates are assumed to be very small and not considered in the formulation. In this chapter we consider only isotropic, homogeneous materials, and the four-node quadrilateral (Q4).
The problem is defined in a domain bounded by T, as illustrated in figure 11.1.
