WebAug 1, 2024 · The displacement constraints referred to as “essential” boundary conditions can be applied through a material layer of volume along the boundary. Similarly, the external tractions referred to as “natural” boundary conditions can be imposed as a body force density distribution also through a boundary layer. WebThe two types of boundary conditions are used: Essential or geometric boundary conditions which are imposed on the primary variable like displacements, and. Natural or force …
