- W594791637 abstract "The mathematical basis of the Finite Element Method (FEM) is given by variational equations which are equivalent to the virtual work equation in the case of structural mechanics. An important improvement of the FEM application is gained by the adaptive mesh refinement. Here, on the basis of a posteriori error estimation, the mesh generation is facilitated considerably because the initial FE- model needs only some simple finite elements. Then, after successive automatic mesh refinements, the accuracy of the solution elevates essentially. To avoid incompatibility at boundaries between a coarse and a fine mesh, the blending functions technique has been used for the construction of the trial functions of the finite elements. The adaptation procedure has been calculated for plane problems and also for three dimensionally folded thin walled structures. In very large FE-models, small adaptive regions may be defined in the vicinity of stress concentration. Several examples show the usefulness of the method for practical problems." @default.
