1. 1. Finite Element Methods for Thin Structures with Applications in Solid Mechanics

   Författare :Karl Larsson; Mats G Larson; Garth N Wells; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; a priori error estimation; finite element method; discontinuous Galerkin; corotation; Kirchhoff-Love plate; curved beam; biharmonic equation; Mathematics; matematik;

   Sammanfattning : Thin and slender structures are widely occurring both in nature and in human creations. Clever geometries of thin structures can produce strong constructions while requiring a minimal amount of material. LÄS MER

3. 2. Reconstruction of stresses in plates by incomplete Cauchy data

   Författare :Jonas Lundgren; Björn Gustafsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : We consider an ill-posed boundary value problem from classical plate theory for the biharmonic equation. The boundary conditions involve incomplete Cauchy data on one part of the boundary and an extra condition on the other part. LÄS MER
