A force/strain relation (incorporating shear effects) for the transverse impact of beams is
established in the frequency domain. Inversion by use of a fast-Fourier-transform (FFT) …

An excitation system, consisting of a concrete foundation and a vibrator, was placed on a
gravelly top layer over a 40 m deep soft clay deposit. The excitation frequency was varied …

Two novel in situ clearance and impact force estimation approaches, one based on a
describing function approach and the other on an optimization approach, are developed for …

It is well known that lightweight floor structures have poor air borne sound insulation and, in
particular, impact sound insulation. In conjunction, raised demands regarding sound …

The paper deals with evaluation of the effects, caused by pounding on the elastic response
spectra. A simple tension opening gap element is added to the well known SDOF system …

Increasing clearances in many mechanical and industrial systems are closely related to
wear. Hence accurate estimation of clearances and impact forces is extremely important in …

A revision to a previously developed method for solving the dynamic-contact problem of a
rigid, smooth striker impacting an elastically supported beam is presented. The revision is …

A new formulation is proposed to model pounding between two adjacent structures, with
natural periods T1 and T2 and damping ratios ζ1 and ζ2 under harmonic earthquake …

The problem of foreign object impact on composite structures has received considerable
attraction in recent years. One aspect in the study of impact is the determination of force …
