Abstract: A Dugdale-Barenblatt model is used to examine the effects of crack closure following a step increase in the applied cyclic loading. Complex function formulation is employed to calculate opening ...

Abstract: A comprehensive approach for computing the lubricant flow as functions of the roughness orientation is presented. By using a mapping function, a periodic, anisotropic surface is transformed into ...

Abstract: This paper presents an improved algorithm for cross-coupling controlled systems. In contrast to the existing algorithms, which must be re-formulated for different types of curves and may be ...

Abstract: This paper presents interpolators that are capable of generating 2D curves in general implicit forms and 3D curves in general parametric forms. In contrast to the existing interpolators, which ...

Abstract: The purpose of this paper is to study the factors that contribute to the dynamic behavior of railway ramp/bridge interfaces. A nonlinear, 100‐ton, freight car vehicle model (gross weight 131.5 tons) and a 50‐ft (15.24‐m) ...

Abstract: This paper presents a method for solving a class of two-dimensional elastic branched crack problems. In contrast to other approaches in the literature, the integral equation presented here enables ...

Abstract: A porous medium model is basically a macroscopic description of the fluid behavior and is considered more appropriate to the mixed lubrication regime. The present work has successfully combined ...

Abstract: A cost estimating model is developed for light rail transit (LRT) and bus rapid transit (BRT) systems to better aid transportation planners and decision makers in the selection process. In evaluating transit systems, cost ...
