Ridley-Ellis, D. (2007). Whack-a-stick discovery

This flash animation is a powerful simulation of the longitudinal vibration of a solid beam (the basic physics behind modern non-destructive methods of testing timber battens to measure stiffness and predict strength.

You can see the effect of str... Read More about Whack-a-stick discovery..

Torsion tests on small and large-scale RHS with circular wall cut-outs (2007)
Presentation / Conference Contribution
Ridley-Ellis, D., Owen, J. S., & Davies, G. (2007, September). Torsion tests on small and large-scale RHS with circular wall cut-outs. Presented at 10th Intl Symp on Tubular Structures (ISTS), Madrid, Spain

The results of small and large-scale torsion tests on rectangular section tubes with circular wall perforations are presented and discussed. Perforations are shown to cause the torsional resistance to be re-duced by up to 60% and stiffness to be redu... Read More about Torsion tests on small and large-scale RHS with circular wall cut-outs.
