The behavior of impacting systems is highly nonlinear and generally numerical analysis
must be resorted to if a quantitative description of the behavior of such systems is required …

Experimental modal analyses of civil engineering structures are performed for various
reasons. One is to assess the condition of the structure. Another is to verify the behaviour of …

Low to moderate speed collision between elastic-plastic bodies results in imperceptible
permanent indentation of the contact surfaces if the bodies are hard. Nevertheless in these …

An experimental method is investigated whereby the strain response from an impacted
beam is sufficient to determine the contacting force. Once the force is known, it is shown how …

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) …

The asymptotically stable motion of two rigid masses separated by a clearance is formulated
most generally when the masses collide periodically. Predictions are shown to agree …

The transient dynamic analysis of constrained mechanical systems may require the solution
of a mixed set of algebraic and differential equations of motion. The usual formulation of …

ABSTRACT A genera] theory is developed for the general stable periodic motion of an
Impact-Pair and impact damper when subjected to a pre-scribed, sinusoidaìly time varying …

In this work multi-modal systems subject to impact are considered. Using energy balance
techniques for an arbitrary contact interval the effects of modal vibration can be included …

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 …
