Results testing parallel to a joint were in keeping with expectations that intact rock strength govern the onset of yielding of the composite test cube. Thus, results to date do not support the hypothesis of an equivalent...

... and were partly altered. Twelve cubic test pieces were cut from the cores. The diameter of the core is about 100 mm. The size of each test cube was 50 mm in each dimension. Four foil swain gauges, of 10 mm length, were attached to each of the six surfaces of the test cubes and each test cube was sealed...
