Adaptive mesh refinement procedures for static and dynamic problems / Selman, A. 

Public ISBD Titre : Adaptive mesh refinement procedures for static and dynamic problems Type de document : texte imprimé Auteurs : Selman, A., Auteur ; Hinton, E., Directeur de thèse Editeur : University College of Swansea Année de publication : 1992 Importance : 95 f. Présentation : ill. Format : 30 cm. Note générale : Thèse de Doctorat : Génie Civil : Swansea, University College of Swansea : 1992 Bibliogr. Annexes 97 - 149 f Langues : Anglais (eng) Mots-clés : Génie  civil  AMR  algorithms  Mesh  REfinement  Plates  using  AMR  Edge  effect Index. décimale : D000892 Résumé : This thesis is concerned with the development, testing and use of finite element based methods in conjunction with adaptive mesh refinement procedures for the solution of three types of static and dynamic stress analysis problems. First, an adaptive mesh refinement procedure is introduced and used in static plate bending finite element analysis based on Mindlin-Reissner assumptions to study the edge effects which occur in plates with certain types of boundary conditions. Several issues of finite element mesh dependence and adaptivity in strain localisation problems are then discussed and illustrated. Finally, adaptive finite element methods for the solution of two dimensional transient dynamic stress analysis problems are developed and tested on some benchmark examples. In all cases cited above there is a need to refine the finite element mesh locally in certain zones either within or at the boundary of the domain under consideration. In the transient problems there is a further problem: these zones will move with time. To produce the required mesh refinement automatically in all cases three ingredients are required: a/ a means for local refinement indication. b/ a technique for converting this refinement information into a desired mesh density, and. c/ an automatic mesh generation facility which produces meshes of the desired mesh density. The methods used for the refinement indication and mesh density prediction vary for the three types of stress analysis considered. However, the mesh generation, in all cases, is carried out using a procedure called the advancing front method.
