Design and fabrication of large-scale testing machine for static and dynamic testing of rock cavity reinforcement is described. The machine is patterned after a smaller prototype developed previously...
Theoretical and Experimental Study of Deep-Based Structures in Intact and Jointed Rock. (2002)
Theoretical and laboratory studies were performed to investigate: (1) effects of lateral confinement and rock specimen-to-tunnel diameter ratio in laboratory testing of reinforced tunnels in rock,...
Laboratory tests were performed on 5/8-inch- (16mm) diameter scale models of cylindrical structures fielded in Mighty Epic. The model structures were tested in 4-inch- (0.1-m) diameter specimens of...
The Influence of Annealing Temperature on the Strain Rate Sensitivity of Copper in Torsion. (1998)
Senseny,P. E., Richman,M. H., Duffy,J.
The effect of annealing temperature on the high strain rate behavior of OFHC copper and a tellurium doped free machining copper is investigated. The annealing temperatures studied include...
