Journal ArticleDOI
Two-dimensional X-ray CT image based meso-scale fracture modelling of concrete
TL;DR: In this paper, a meso-scale finite element model with realistic aggregates, cement paste and voids of concrete is developed using micro-scale X-ray Computed Tomography images.
Journal ArticleDOI
On relationships between the mechanical properties of recycled aggregate concrete: An overview
J. Zh. Xiao,Jiabin Li,Ch. Zhang +2 more
TL;DR: In this paper, a detailed investigation is conducted to analyze the relationships between the mechanical properties of recycled aggregate concrete (RAC) based on a large number of experimental results published worldwide in literature from 1985 to 2004.
Journal ArticleDOI
Mechanical properties of confined recycled aggregate concrete under axial compression
TL;DR: In this paper, the results of axial compression tests on recycled aggregate concrete (RAC) confined by steel tubes and RAC confined by glass fiber reinforced plastic (GFRP) tubes were presented.
Journal ArticleDOI
Dynamic analysis of sandwich beams with functionally graded core using a truly meshfree radial point interpolation method
TL;DR: In this paper, the displacement field is approximated by the radial point interpolation method (RPIM) regardless of predefined mesh, and the domain integrals are evaluated by the so-called Cartesian transformation method (CTM) to obviate the need for a background cell.
Journal ArticleDOI
Fracture analysis of functionally graded materials by a BEM
TL;DR: In this article, a boundary element method (BEM) based on a boundary-domain integral equation formulation is developed for crack analysis in two-dimensional (2D), continuously nonhomogeneous, isotropic and linear elastic functionally graded materials (FGMs).
