Processing and properties of recycled aggregate concrete
… various mixture batches. In addition, ring and dog bone tests were studied when the specimen is restrained and is affected by internal tensile stress. With using 74% initial moisture states of recycled coarse aggregates, the compressive strength was similar to that of normal concrete and the …

Effect of Postmortem Time and Preservation Fluid on the Tensile Material Properties of Bovine Liver Parenchyma
… blocks, or slices of tissue. Multiple parenchyma dog-bone samples from each liver were tested once to failure at three time points: ~6hrs, ~24hrs, and ~48hrs postmortem. The data were then analyzed to determine if there were significant changes in the material properties with respect to postmortem …

Fretting fatigue Behaviour of Inconel 718 at room and high Temperature
… used, consisting of a rectangular cross-section "dog-bone" specimen pressed against a cylindrical pad. The setup was assembled using a device commonly referred to as a “fretting bridge.” Both plain fatigue and fretting fatigue tests were carried out under different levels of axial and normal load, …
