Development of an intermediate strain rate compression testing machine
The further development of the wedge bar Intermediate Strain rate Tester (IST) presented by Cloete and Oxtoby [1] is presented in this dissertation. The concept uses a wedge mechanism to deform 5 mm diameter, 5 mm long specimens at strain rates in the region of 10 s, up to strains of 30. As impact …

Experimental Techniques for Shear Testing of Thin Sheet Metals and Compression Testing at Intermediate Strain Rates
… of this work is to develop methods to generate experimental data that populate material models for numerical simulations. The new simple shear specimen, based on ASTM B831, can be tested in both quasi-static and dynamic conditions using a servo-hydraulic load frame and tension Kolsky bar, …

A Non-linear Visco-elastic Model for Dynamic Finite Element Simulation of Bovine Cortical Bone
… three-dimensional models, but do not accurately capture the transition in behaviour in the intermediate strain rate region, while Cloete et al. developed a phenomenological model which captures the intermediate strain rate behaviour in one dimension. This work aims to verify and extend …

An experimental investigation into the anisotropic behaviour of bovine femoral cortical bone
… the behaviour of cortical bone, knowledge of the strain rate dependent behaviour is required. Many authors have investigated these properties, however, the literature appears to be ambiguous and incomplete, with little focus being placed upon the intermediate strain rate regime (1s⁻¹ to 100s⁻¹). …

An experimental investigation of interspecies variation in mechanical properties of cortical bone
… the relationship of material properties to strain rate within each species. This information is valuable for use in modelling. Testing was performed quasistatically and at the high end of the intermediate strain rate regime. These higher rate tests were performed on a modified Split …

Collective dynamics in flowing suspensions of swimming micro-organisms
… the orientation of the particles. We demonstrate that the rate of damping is direction-dependent: it is fastest in the flow direction, but slowest the direction perpendicular to the shear plane. Consequently, transitions from three- to two- to one-dimensional instabilities are observed to …
