Isogeometric analysis enhanced by the scaled boundary finite element method [PDF]

, 2015
By leveraging the information of a typical CAD model in the analysis, the intensive process of discretization can be circumvented. This unification has led to the 'Isogeometric Analysis' (IGA) (Hughes etal., 2005).

Fast prediction of concrete equivalent modulus based on the random aggregate model and image quadtree SBFEM

Science and Engineering of Composite Materials
To evaluate the mechanical property of concrete materials rapidly, a fast prediction model of the concrete equivalent modulus is proposed based on the random aggregate model and scaled boundary finite element method (SBFEM).

Analysis of the Electrostatic Field in Ring-type Domain by SBFEM with Schur Decomposition

工程科学与技术, 2013
:Scaled boundary finite element method (SBFEM) was applied to solve the boundary value problems of the electrostatic field in coaxial-cable, i.e., ring-type domain. To avoid the singularity in eigenvalue method, Schur decomposition was employed to update
