Numerical Simulation of the Dynamic Frictional Contact Problem for Crack Slip Based on the Multidimensional Space Method
Publisher: American Society of Civil Engineers
Abstract: The extended finite-element method (XFEM) was proposed to simulate the problem of crack growth without any remeshing. In this paper, the penalty function method is introduced to deal with the contact constraints, and the ...
Field-Enriched Finite-Element Method for Simulating Crack Propagation and Coalescence in Geomaterials
Publisher: ASCE
Abstract: A field-enriched finite-element method for simulating crack propagation and coalescence in geomaterials is proposed in this work. In the novel numerical method, the physical position of the crack is characterized by the ...
Novel Three-Dimensional Sarma Method with Vertical Slices for Stability Analysis of Rock Slopes
Publisher: ASCE
Abstract: In general, the traditional Sarma method is two-dimensional (2D). In nature, slopes are three-dimensional (3D) problems. However, the 3D Sarma method is rarely proposed and used in rock slope engineering. In this paper, ...
Nonlinear Creep Model for Rocks Considering Damage Evolution Based on the Modified Nishihara Model
Publisher: ASCE
Abstract: In general, the microdefects in rocks obey Weibull distribution. Based on the laws of statistics of microdefects in rocks, the relationship between the damage and the strain is established. Moreover, by considering ...
Numerical Simulation of Crack Propagation and Coalescence in Quasi-Brittle Materials under Compression Using the Field-Enriched Finite-Element Method
Publisher: American Society of Civil Engineers
Abstract: In this paper, the field-enriched finite-element method is developed to simulate crack evolution of quasibrittle materials under compression by considering two kinds of fracture criteria: the maximum circumferential stress ...
Reliability Analysis of Seismic Slope Stability with Uncertain Probability Distributions
Publisher: ASCE
Abstract: The probability density function or cumulative distribution function of shear strength parameters is commonly unknown, and the first-order reliability method, second-order reliability method, and Monte Carlo simulation ...
Wedge-Failure Analysis of the Seismic Slope Using the Pseudodynamic Method
Publisher: American Society of Civil Engineers
Abstract: In the past, the pseudostatic method was the most common method used to evaluate stability of the slope under seismic loads. Through the method, static forces acting on the center of gravity of a sliding body are used to ...
