Computational modeling of fracture in concrete using a meshfree meso-macro-multiscale method

Monte Carlo simulations of mesoscale fracture modelling of concrete with random aggregates and pores

“…Its mechanical behaviour is a result of multiple mechanisms occurring at different length scales, from macro, meso to microscale and even atomic or sub-atomic scales. Therefore, multi-scale experiments and simulations of concrete has become a hot research area offering more accurate insights to the mechanical behaviour of concrete material and structures [1][2][3][4]. A current focus has been stochastic heterogeneous modelling of concrete considering its multiple phases and interactions at micro and meso scales [5][6][7][8][9][10][11][12][13].…”

Multiscale hydro-thermo-chemo-mechanical coupling: Application to alkali–silica reaction

“…In addition, the adaptive domain decomposition method was used to analyze the multiscale failure in the concrete. Ghosh and Chaudhuri [7] developed a multiscale failure model for concrete, where the material far from the fracture process zone was described by the homogenized elastic model, while a nonlinear model was used in the fracture process zone. The fracture at the mesoscale was modeled by CZM in the context of an enriched partition of unity meshfree method.…”

Meso-scale image-based modeling of reinforced concrete and adaptive multi-scale analyses on damage evolution in concrete structures

“…As shown in Fig. 10, in order to facilitate the adaptive multi-scale method for programming design and analysis, the sub-domains are divided into a set of representative volume elements (RVEs) such as RVE macro ; RVE mesoÀx ðx ¼ fu; d; l; r; mgÞ, and RVE transÀx ðx ¼ fu; d; l; rgÞ, which respectively describe macro- 1 For interpretation of color in Fig. 6, the reader is referred to the web version of this article.…”

“…Since reinforced concrete (RC) is widely used in engineering field [1,2], the failure mechanisms of RC structures have been studied by many researchers [3]. Baskar et al studied the failure behavior of steel-concrete composite plate girders under negative bending and shear loading using finite-element analysis [4].…”
