...Ba-Thanh Vu; Viet Hai Hoang Purpose This paper aims to investigate the effects of steel fiber position, inclination angle and length on the fracture behavior of steel fiber reinforced concrete (SFRC), while reducing the computational burden associated with high-fidelity phase-field fracture...

...Ba-Thanh Vu; Hung Le-Quang; Qi-Chang He Purpose The phase-field method of interfacial damage is used to simulate the damage in composite structures containing the brittle orthotropic materials and their interface. Design/methodology/approach In the brittle fracture modeling, the strain tensor...

...Wei Zhang; Peitong Cong; Kang Bian; Wei-Hai Yuan; Xichun Jia Purpose Understanding the fluid flow through rock masses, which commonly consist of rock matrix and fractures, is a fundamental issue in many application areas of rock engineering. As the equivalent porous medium approach is the dominant...

...Kyungmok Kim; Jean Geringer; Bernard Forest Purpose The purpose of this paper is to describe finite element modelling for fracture and fatigue behaviour of zirconia toughened alumina microstructures. Design/methodology/approach A two‐dimensional finite element model is developed with an actual...

...Y T Feng; Nuno Monteiro Azevedo; José V. Lemos Purpose The rigid spherical particle models proposed in the literature for modeling fracture in rock have some difficulties in reproducing both the observed macroscopic hard rock triaxial failure enveloped and compressive to tensile strength ratio...

...Y.T. Feng; Ba Danh Le; Georg Koval; Cyrille Chazallon Purpose The purpose of this paper is to use the discrete element method (DEM) to model the fracture behaviour of brittle materials in 2D. Design/methodology/approach The material consists of a set of particles in contact with a close‐packed...

...Jorge Palma Carrasco; José Maria Andrade Barbosa; Antonio Almeida Silva; Marcos Antonio da Silva Irmão Purpose The purpose of this paper is to present a numerical simulation of the hydrogen atomic effect on the steels fracture toughness, as well as on crack propagation using fracture mechanics...

... (2002) and Galić et al. (2008) . In the first part of the paper, the constitutive equations of the fracture and plastic models are presented and include the equations describing the combination of these two material models. In the second part, the performance of the material models...

... Significant reduction in computational cost is achievable using a master‐slave procedure to link seepage and fracture network‐flows and an explicit‐explicit subcycling scheme. Special attention is focused on the investigation of the influence of plastic zones in oil production problems. Hydraulic...

...Henryk Sanecki; Andrzej Piotr Zieliński Purpose To provide more convenient tools for the investigation of real objects with different forms and positions of cracks, which requires fracture analysis of engineering structures. Design/methodology/approach A method which uses the Trefftz‐type...

...Luciano Simoni; Stefano Secchi This paper presents a mathematical model for the analysis of cohesive fracture propagation through a non‐homogeneous porous medium. Governing equations are stated within the frame of Biot's theory, accounting for the flow through the solid skeleton, along the fracture...

...J.E. Bolander, Jr; H. Hikosaka; W.‐J. He A planar lattice network of beam elements is used to study the mechanisms of fracture in cement‐based materials. Beam properties are controlled by a nonlinear elastic fracture law which roughly accounts for three‐dimensionality of the material and fracture...
