As the temperatures increase to 120 °C, 160 °C and 200 °C, the tensile strength of the basalt fiber decreased by 2.0%, 5.6% and 8.3%, respectively.
2009-02-23· 8.2 TENSILE STRENGTH The tensile strength of soil is very low or negligible and in most analyses it is considered to be zero. In contrast a number of direct or indirect tensile strength tests are commonly carried out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force.
A measured deformation modulus for ambient pressure in the vertical direction, 20 GPa, is 1.5–3 times larger than that in the horizontal directions, 13.5 and 6.5 GPa, reflecting strength anisotropy due to column or block geometry for one particular basalt.

2019-11-23· Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size.
The compressive strength of Phosphor Bronze is directly proportional to the tensile strength, For example 1/2 hard phosphor bronze has a Tensile Strength of 60 to 75 ksi and a Yield Strength of 45 to 70. For typical engineering calculations, the compressive strength can be considered equal to the yield strength.
Basalt rebar reinforcement is an alternative to steel and fiberglass for reinforcing concrete. Made from volcanic rock, basalt rebar is tougher and stronger than steel with a higher tensile strength. Much lighter than steel, 89% percent in fact! One man can easily lift a 100 meter / 328 foot coil of 10 mm basalt rebar.
That all depends on the material For most all metals, tensile strength is stronger by about factor of 1.7 For most metals tensile strength is equal to compression strength For concrete, both comppression strength and shear strength are higher than tensile strength For many composites, tensile strenght is higherthan compression strength
