A PSBFEM Approach for Solving Seepage Problems Based on the Pixel Quadtree Mesh
Geofluids, Volume 2023, Issue 1, 2023., 2023 This paper presents a PSBFEM approach that integrates the quadtree mesh generation technique based on digital images for solving seepage problems. The quantitative representation of the distribution of geometrical information and material parameters is achieved by utilizing the color intensity of each pixel, which can then be applied to seepage ...

Scaled Boundary Finite Element Method for Thermoelasticity in Voided Materials [PDF]
, 2015 The scaled boundary finite element method (SBFEM) is presented to study thermoelastic problems in materials with voids. The SBFEM combines the main advantages of the finite element method (FEM) and the boundary element method (BEM).

International Journal for Numerical Methods in Engineering, Volume 123, Issue 5, Page 1228-1252, 15 March 2022., 2022 Abstract This contribution presents an isogeometric approach in three dimensions for nonlinear problems in solid mechanics and structural dynamics. The proposed approach aligns with the boundary representation modeling technique in CAD. Isogeometric analysis is combined with the parameterization of the scaled boundary finite element method. In this way,

Modelling multiple cohesive crack propagation using a finite element-scaled boundary finite element coupled method [PDF]
, 2009 This paper presents an extension of the recently-developed finite element-scaled boundary finite element (FEM-SBFEM) coupled method to model multiple crack propagation in concrete. The concrete bulk and fracture process zones are modelled using SBFEM and

Journal of Mathematical Sciences and Modelling, 2018 To analyse soil-structure-interaction problems, often unbounded domain has to be taken into account. Since the finite element method (FEM) does not provide open boundary itself the scaled boundary finite element method (SBFEM) which fulfils the radiation
