Aug 01, 2013 Porosity is a significant physical feature of rocks due to water absorption that causes decrease in the strength. The basalt of the study area can be described as “highly porous” and ignimbrite as “extremely porous” according to the classification by Anon (1979).The average UCS of basalt is determined as 26.65 MPa.For the ignimbrite, the lowest UCS is observed in the black …

Jun 25, 1993 Values of tensile and cohesive strength for the basaltic rock mass are approximately one to two orders of magnitude lower than corresponding values for intact basalt. Temperatures comparable to those at the Venus surface may slightly increase the deformation modulus but decrease the compressive strength of the rock mass.

out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force. The tensile strength is then calculated as the failure tensile force divided by the cross-sectional area. It has been found that a rock core will split along a diameter when loaded on its side in a compression machine.
