Abstract: The solution of an isoparametric, overdetermined formulation of the Helmholtz Integral is presented and demonstrated in three examples of acoustic radiation from spherical sources. The placement ...

Abstract: A formulation of friction force in the interface of a friction pair is developed considering the mechanical components arising from the elastic and plastic deformations of the asperities and ...

Abstract: In the commonly used definition of acoustic “radiation efficiency” of a plate, it is assumed that the amplitude of a traveling harmonic wave on the plate is kept constant, independent of the ...

Abstract: This paper is concerned with the behavior of sound radiation from bending waves of an infinite plate in a fluid with viscous and thermal losses. The radiation field variables are obtained ...

Abstract: The effect of refraction by a flow boundary layer on the radiation of sound from a bending wave on a plate is investigated. Based on the relative velocities of the bending wave and the ...

Abstract: The resonance features present, and observable, in the form-functions of submerged, fluid-filled, elastic, thin shells, usually appear combined with smooth, undesirable, background components that ...

Abstract: A theoretical analysis of transient sound radiation from a clamped circular plate is given using a pressure impulse response method. The vibration response of the plate to a transient point ...

Abstract: The dynamic behavior of a four-bar mechanism with a clearance at any one of its connections is described using a quasi-static model. Prediction of separation at the joints is based on the ...

Abstract: A finite element method is developed to treat the steady-state vibration of two axisymmetric structures—a base substructure and an attached damper substructure—that are driven by traveling wave ...
