RISNumerical 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 ...
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 ...
An Analytical Investigation of the Topographic Amplification Effects of Slopes under Seismic Loads
Publisher: ASCE
Abstract: In this paper, an analytical approach is proposed to investigate the topographic amplification effects of slopes under seismic loads. The method of region decomposition and matching was adopted to decompose the whole ...
Experimental Study of Modal Characteristics for Heated Composite Structures
Publisher: ASCE
Abstract: Aircrafts with high Mach speeds are exposed to severe thermal load, which affect the performance of aircraft components. Although several experimental studies have been performed on the mechanical behavior of aircraft ...
Mechanical Properties of High-Modulus Asphalt Concrete Containing Recycled Asphalt Pavement: A Parametric Study
Publisher: ASCE
Abstract: The recycling of asphalt pavement is a widespread practice around the world owing to its significant social, economic, and environmental advantages. High-modulus asphalt concrete (HMAC) possesses excellent rutting resistance ...
Risk-Based Maintenance Planning for Rail Fastening Systems
Publisher: American Society of Civil Engineers
Abstract: Failures in rail fasteners can lead to misalignments of the rails and even cause a train derailment. Current inspection and maintenance regimes for rail fasteners, however, do not adequately address the credible failure ...
Three-Dimensional Stability Analysis of Bank Slopes with Reservoir Drawdown Based on Rigorous Limit Equilibrium Method
Publisher: ASCE
Abstract: The fluctuation of reservoir water levels has significant impact on bank slope stability near a reservoir. Therefore, it is necessary to analyze the stability of bank slopes with reservoir drawdown. In this paper, a novel ...

Quantitative Analysis of Concrete Lining Damage in Field Canals by Frost Heave Using a Water–Heat–Mechanical Coupling Model
Publisher: ASCE
Abstract: Concrete linings of field canals are seriously damaged by frost heave in the north of China. However, the mechanism causing lining damage is too complex to be described quantitatively, and present models are insufficient ...
