![]() Each triangular element has three nodes, (i.e., one node at each corner). We consider such an area meshed with triangular elements. At each point there can be only one temperature. ![]() An example is the temperature distribution in a plate. (a scalar quantity, not a vector quantity). The physical domain considered is geometrically a 2-Dimensional domain, i.e., an area with uniform thickness and the single variable can be one of pressure, temperature, etc. It is defined to be a state of strain in which the normal to the xy plane and the Stress ( t )directed perpendicular to the plane are assumed to be zero. It is defined to be a state of stress in which the normal stress ( s ) and shear ![]() ![]() The 2d element is extremely important for the Plane Stress analysis and Plane The basic element useful for two dimensional analysis is the Two dimensional elements are defined by three or more nodes in a two dimensional ![]()
