Values greater than one are quite rare, seen as unusual and barely explained. Previous experimental research conducted in Australia has shown consistent and systematic values of the normal restitution coefficient greater than one. This was tentatively explained by a combination of parameters such as low impacting angle, rotational energy and block angularity. The study presented in this paper aims at (1) identifying the critical parameters conducting to high kn values and (2) at explaining the associated motion mechanisms. The objective was reached with values of kn up to almost 2. In addition, the study has confirmed the significance of low impacting angle, rotational energy and block shape in this context.]]> Wed 11 Apr 2018 11:19:49 AEST ]]> Installation, calibration, and application of dielectric sensors in laboratory studies of compacted unsaturated granular materials https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:13852 3/m3.

The model is based on theoretically-derived conversion factors used to turn the critical work required to fail disc samples in quasi-static indirect tension into the critical kinetic energy to cause failure of spheres at impact in drop tests. The mechanistic conversion factors specifically account for the shape and size of the specimens tested and the increase of strength under dynamic loading (strain rate effect). Three series of drop tests were conducted (on spheres of three different diameters) and complemented by extensive material characterisation testing in order to validate the novel predictive model. The variability of material properties was characterised, and it was found that the material strength found by the characterisation tests generally follows a Weibull form, but the survival probability distribution of the drop tests seems to be linear. The predicted conversion factors were first compared against their experimental counterparts before validating the prediction of survival probability of the spheres upon dynamic impact (in drop tests). It was found that it is possible to predict the survival probability of artificial rock of three different diameters (50 mm, 75 mm, 100 mm) and two different strengths upon impact solely from the statistical information coming from Brazilian tests and with an average relative error of less than 9%.]]> Fri 10 Jun 2022 14:46:30 AEST ]]> X-Ray microtomography of mercury intruded compacted clay: An insight into the geometry of macropores https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52996 Fri 03 Nov 2023 16:06:17 AEDT ]]>
