tests indicated,that the rock within each rock type was quite uni- form. Results of the unconfined compressive strength tests on basalt indicated that as the loading rate was increased from 1 to 1.60 x 10 psi/sec, ultimate strength, total axial strain, and Young's modulus of elasticity increased. Total diametral strain decreased as.

perpendicular to an imaginary plane passing through a rock mass. It is considered positive if it would cause shortening of material along axis of stress tensor. If normal stress is negative it would potentially cause a stretching along this direction. The symbol σ is used to represent normal stress.

Institute of Rock Structure and Mechanics, Academy of Sciences of the Czech Republic, V Holesovicˇka´ch 41, 182 09 Prague 8, Czech Republic. ABSTRACT: Heat resistant composites reinforced with continuous basalt fibers were made . The shear modulus values increase after pyrolysis to 7508C, which expresses the.

evaluated by using a poro-elastic relationship be- tween elastic moduli of porous medium with ﬂuid-. ﬁlled pores and the moduli of the same medium with empty pores derived by Gassmann (1951). Gassmann's relationship gives the saturated rock bulk modulus in terms of the bulk moduli of dry porous medium, solid mineral.

tests indicated that the rock within each rock type was quite uni- form. Results of the unconfined compressive strength tests on basalt indicated that as the loading rate was increased from 1 to 1.60 x 107 psi/sec, ultimate strength, total axial strain, and Young's modulus of elasticity increased. Total diametral strain decreased.
