RISParametric Instability in a Taut String With a Periodically Moving Boundary
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Parametric instability in a taut string with a periodically moving boundary, which is governed by a onedimensional wave equation with a periodically varying domain, is investigated. Parametric instability usually occurs ...
Dynamic Stability of a Class of Second Order Distributed Structural Systems With Sinusoidally Varying Velocities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Parametric instability in a system is caused by periodically varying coefficients in its governing differential equations. While parametric excitation of lumpedparameter systems has been extensively studied, that of ...
A New Global Spatial Discretization Method for Calculating Dynamic Responses of Two-Dimensional Continuous Systems With Application to a Rectangular Kirchhoff Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new global spatial discretization method (NGSDM) is developed to accurately calculate natural frequencies and dynamic responses of two-dimensional (2D) continuous systems such as membranes and Kirchhoff plates. The ...
Fatigue Failure Analysis of Cracks near the Sole Plate of a Half-Through Steel-Arch Bridge
Publisher: American Society of Civil Engineers
Abstract: A fractured bolt connecting the bearing and the stiffening girder of a half-through steel-arch bridge, with a main span length of 113 m, which was opened for public in September 1996, was found in October 2013 during ...
