Impacts in mechanical systems are ubiquitous. These can be intrinsic; such as suspension cables in bridges acting as one-sided springs, unintentional; such as lateral 'Hunting' motions of trains causing loss of contact with the track, a result of wear or manufacturing errors; such as dead zones or gear rattles or...

Vibrations of an autoparametric system, composed of nonlinear mechanical oscillator with an attached damped pendulum, around 1:2 resonance region, are investigated in this work.

New type of static friction model containing hysteresis is presented.

A talk on the interaction of silicon design and progress in communications technologies, particularly mobile/wireless devices. Prof Boeck is a member of staff at Berlin University. Georg will be accompanied by Dr Frank Henkel of IMSL. Frank has been involved in a large number of EC funded...

Single–molecule tests on DNA in a magnetic tweezer experiment allow the molecule to be stretched and twisted. Under increasing twist the DNA buckles locally and forms a ply (plectoneme) which grows at right–angles to the loading axis. Interpreting this in terms of elastic–rod theory allows the estimation of important parameters...

Nonlinear normal vibration modes of a semi-infinite slender beam on elastic foundation with unilateral contact are addressed using the method of multiple scales.

A good correlation between the experiments and theory allowed to unfold the complex forced dynamics of a sagged cable triggered by a divergence-Hopf codimension two bifurcation.

The Molecular Dynamics (MD) is a vast research field attempting to model natural phenomena on a wide span of length&time scales ranging from atomistic (angstrom: 10-10m) to tissue/material fragment(micrometer:10-6m) length scales as well as from picoseconds (QM/MM simulations) to microseconds (protein folding, membrane protein function) time scales.
