The theoretical model for the impact of polycrystalline graphite beams previously presented by the authors has been improved by the addition of an empirical model of the internal friction of the specimen. This takes the form of a velocity dependent d

A method is described for solving the Volterra integral equation of the 2nd kind, which models normal impact between a falling hemispherically surfaced impactor and a thin circular plate. The model includes the vibration induced in the plate as the r

It is difficult to interpret acoustic emissions generated within stressed fibre composites. To obtain a better understanding of the characteristic features of acoustic emission at source in carbon fibre reinforced plastics, a number of experiments ha

A new method is described for the calculation of the time-dependent forces and stresses in a polycrystalline graphite beam subjected to transverse impact. Unlike earlier methods, which consider the contact area to be infinitesimal, the present method

A study of the optical domain and twin structure in single crystals of YBa 2 Cu 3 O 7-δ has shown the presence of interesting features of the microstructure in regions where two sets of orthogonal twins intersect. The observed features are interpret

A lead break source and an impactor source have been used to simulate two different types of acoustic emission events in unidirectional carbon fibre reinforced plastic. The observed transient signals were detected after travelling different distances

While much attention has been focused on predicting the rate of deposition of particles from turbulent gas flow, relatively little work has been done on simulating the morphology of the deposit. A two-dimensional inertial deposition model has been us

Measurements have been made of the absorption properties of a silicone fluid in a silicone elastomer, Aircast 3700, at temperatures between 0 and 150 °C. It was found that the diffusivity could be described by Arrhenius' law. The saturation fluid co
