Identification of dynamic properties of materials for the spent nuclear fuel package at elevated temperatures
… for the nuclear fuel package and the appropriate testing systems were identified [15]. Second, fixtures for tensile testing at elevated temperatures using two machines, namely MTS and Instron Dynatup testing machines were designed and manufactured to make them compatible with the room temperature …

Implementation of a testing and initialization algorithm for the generalized tree structure
… structure of a generalized tree using, as the testing machines, a set of generalized sequential trees. It is shown that the testing machine can be implemented on a set of trees of the same depth as that of the tree which is being tested. Modifications are made to the generalized tree structure …

Flexure modulus of elasticity in living branch wood
… kept at ambient room temperature or 21.1 C. Two testing machines were used to measure MOE and subsequently compared to one another. In general, the data obtained from the Fakopp meter calculated MOE higher than the data from the universal test machine (UTM), but had a smaller standard error. The …

Design and analysis of a composite wire-socket attachment
… An experimental investigation using tensile testing machines is performed, testing anchorages of 1, 7 and 19 wires. Conventional strain gage and acoustic emission measurement techniques are used. The tests are essential in determining the failure load and failure mode. However, the …
