RISNumerical Analysis of Transient Wave Propagation in Nonlinear One Dimensional Waveguides by Using the Spectral Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, transient wave propagation in nonlinear onedimensional (1D) waveguides is studied. A complete nonlinear (CN) 1D model accounting for both axial and transverse displacements is developed and geometric and ...
Alternating Frequency–Time Finite Element Method: High Fidelity Modeling of Nonlinear Wave Propagation in One Dimensional Waveguides
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a spectral finite element method (SFEM) based on the alternating frequency–time (AFT) framework is extended to study impact wave propagation in a rod structure with a general material nonlinearity. The ...
Numerical Investigation of Lateral and Axial Wave Propagation in Drill Strings for Stability Monitoring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the propagation of lateral waves and axial acoustic waves in a drillstring are studied by using a new numerical method and a stability monitoring scheme is proposed. The drillstring is modeled as a linear ...
