Isogeometric Boundary Element Analysis with elasto-plastic inclusions. Part 1: Plane problems
In this work a novel approach is presented for the isogeometric Boundary Element analysis of domains that contain inclusions with different elastic properties than the ones used for computing the fundamental solutions. In addition the inclusion may exhibit inelastic material behavior. In this paper only plane stress/strain problems are considered. In our approach the geometry of the inclusion i...
متن کاملIsogeometric Boundary Element Method with Hierarchical Matrices
In this work we address the complexity problem of the isogeometric Boundary Element Method by proposing a collocation scheme for practical problems in linear elasticity and the application of hierarchical matrices. For mixed boundary value problems, a block system of matrices – similar to Galerkin formulations – is constructed allowing an effective application of that matrix format. We introduc...
متن کاملA New Integration Algorithm for the Finite Element Analysis of Elasto-plastic Problems
The Finite Element analysis of the elastic-plastic behavior is of fundamental importance in automobile industry. To predict accurately the final geometry of the structure and the distribution of strain and stress, accurate integration of the constitutive laws over the strain path is essential. Our objective in this paper is to develop an effective and accurate stress integration scheme for the ...
متن کاملError estimates for elasto-plastic problems
— Under some reasonable smoothness assumpfions on the displacements, we are able to dérive an error estimate of the form ||a — <7h||L2{fl)^ Ch, for the approximation of the stress field a in some problems in elasto-plasticity. Using the same ideas, we als o find a piecewise line ar approximation of Mosolov's problem, for which we still get an 0 (h) error estimate.
متن کاملA Finite Element Study of Elasto-plastic Hemispherical Contact
This work presents a finite element study of elasto-plastic hemispherical contact. The results are normalized such that they are valid for macro contacts (e.g., rolling element bearings) and micro contacts (e.g., asperity contact). The material is modeled as elastic-perfectly plastic. The numerical results are compared to other existing models of spherical contact, including the fully plastic c...
