“…A fracture criterion was proposed by Camacho and Ortiz (1996) for the mixed mode fracture and widely used in literature. The cohesive fracture model has been widely used in fracture mechanics problems, including: the quasi-static crack propagation of saturated porous media by Simoni and Secchi (2003), Schrefler et al (2006) and Secchi et al (2007), the cohesive crack growth of brittle materials by Song et al (2006), Birgisson et al (2008) and Khoei et al (2009), and the dynamic fracture propagation of saturated porous media by Khoei et al (2010).…”

Modeling the water flow in cohesive fracture is a fundamental issue in the crack growth simulation of cracked concrete gravity dams and hydraulic fracture problems. In this paper, a mathematical model is presented for the analysis of fracture propagation in the semi-saturated porous media. The solid behavior incorporates a discrete cohesive fracture model, coupled with the flow in porous media through the fracture network. The double-nodded zero-thickness cohesive interface element is employed for the mixed mode fracture behavior in tension and contact behavior in compression. The modified crack permeability is applied in fracture propagation based on the data obtained from experimental results to implement the roughness of fracture walls.

“…This microcracking phenomenon consumes a part of the external energy introduced by the applied load, and the resulting microcracks have a variable orientation with respect to the main crack plane. Furthermore, the density of microcracks generally decreases with increasing distance from the face of the main crack (Birgisson et al, 2008). The main crack, or macrocrack, may propagate into several branches due to the heterogeneity of asphalt concrete; more energy will be consumed in the formation of new crack branches.…”

a b s t r a c tA heterogeneous fracture approach is presented for modeling asphalt concrete that is composed of solid inclusions and a viscous matrix, and is subjected to mode-I loading in the fracture test configuration. A heterogeneous fracture model, based on the discrete element method (DEM), is developed to investigate various fracture toughening mechanisms of asphalt materials using a high-resolution image processing technique. An energy-based bilinear cohesive zone model is used to model the crack initiation and propagation of materials, and is implemented as a user-defined model within the discrete element method. Experimental fracture tests are performed to investigate various fracture behavior of asphalt concrete and obtain material input parameters for numerical models. Also, bulk material properties are necessary for each material phase for heterogeneous numerical models; these properties are determined by uniaxial complex modulus tests and indirect tensile strength tests. The main objective of this study is to integrate the experimental tests and numerical models in order to better understand the fracture mechanisms of asphaltic heterogeneous materials. Experimental results and numerical simulations are compared at different test conditions with excellent agreement. The heterogeneous DEM fracture modeling approach has the potential capability to understand various crack mechanisms of quasi-brittle materials.

“…Additionally, it has been widely used for determining the fracture parameter K IC , and its potential application in the mixed mode fracture test has been investigated [5][6][7][8][9]. e investigation of the SCB specimen mainly includes fracture toughness testing and determining the fracture parameters [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], discussing and revising the limitations of the extension criteria [11,13,16,25,29,30], and numerically predicting the fracture path [14,20,23,27,[31][32][33]. Owing to the limitation of the specimen shape, the abovementioned studies focused on the fracture parameters of mode I, mode II, and mixed mode I/II.…”

This study used numerical analysis to carry out a large number of numerical model calculations based on a new semicircular bend (SCB) model. Instead of existing numerical computation methods (J-integral), the M-integral method was used to calculate the mixed mode fracture parameters (KI, KII, and KIII), investigate the influence of the geometry and material parameters on the fracture behavior under mixed mode I/III loading, and predict the fracture path. The results revealed that the limitations in the scope of the mixity parameter Me in the previous studies can be overcome to a certain extent. The range of Me was established under different Poisson ratios and can be used as a reference for actual material testing. The simulation path is in good agreement with the experimentally obtained fracture path, and the proposed method can be used to simulate the fracture path under mixed mode I/III loading.
