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.

A study of strength and deformation measurements for basaltic rocks, along with consideration of the influence of fracturing using a rock mass classification system, documents the range of brittle response for basaltic rock masses. Although basalts vary widely in composition and other physical factors, many of the properties of a basaltic rock mass appear to vary within a factor …

Brittle strength of basaltic rock masses with applications to Venus. Schultz, R. A. Abstract. Laboratory measurements of rock deformation in the brittle regime provide constraints on the response of rocks to stress. These values are essential parameters in tectonic models of near-surface deformation because they influence both the stress state ...

Brittle strength of basaltic rock masses with applications. The properties of basaltic rock masses provide a more precise estimate of the strengths of basaltic lava flows on the terrestrial planets than other, more widely used approaches (intact rock or frictional strength of a through‐going surface).

Rock hardness property is usually measured to determine the compressive fracture strength, to determine whether a rock is a soft rock or a hard rock. T. The rock hardness of basalt is 6 as per the Mohs scale and can be observed through a combination of its compressive strength. Generally, 100-300 Mpa or Megapascal is the compressive strength.
