Abstract: An unbalanced rotor dynamic model supported on ball bearings is established. In the model, three nonlinear factors of ball bearing are considered, namely, the clearance of bearing, nonlinear ...

Abstract: In this paper, a new rotor-ball bearing-stator coupling system dynamics model is established for simulating the practical whole aero-engine vibration. The main characteristics of the new model ...

Abstract: This paper investigates the influence of bond slip on crack spacing in reinforced concrete. A bond-link element is used to account for the influence of the bond slip between the concrete and the reinforcing steel. Following ...

Abstract: This paper investigates the minimum and maximum crack spacings in concrete pavements from the energy viewpoint and explores mechanisms that control spacing. An analytical model, which is composed of two cohesive cracks and ...

Abstract: In this technical note, power flow between two oscillators with spring and damping (nonconservative) couplings is introduced, and its relationship with energies stored in the two oscillators is established. It is shown ...

Abstract: The interface crack between two dissimilar materials subjected to a tension load was analyzed using the finite element method in order to study the “open” and “closed” crack tip formulations ...

Abstract: The aim of this work is to develop an efficient method for computing pulsed laser bending. During pulsed laser bending, thousands of laser pulses are irradiated onto the target. Simulations ...

Abstract: A general finite element method of analyzing the nonlinear effects of instability and yielding on the biaxial bending and torsion of steel I‐section members with residual stresses and geometrical imperfections is presented. ...

Abstract: In the current study, a theoretical basis is established for interpreting and correlating the optical caustic patterns with the transition of the crack-tip stress and strain fields under ...

Abstract: The effect of the electrical pulse width and the fuel temperature on dynamic flow and static flow rate of a gasoline fuel injector has been numerically and experimentally investigated. In ...
