Torsional and tensile actuation of these hybrid muscles results from dimensional changes of a yarn guest. The twist-spun nanotubes confine this actuating guest in both solid and molten states and provide the mechanical strength and helical geometry enabling large-stroke torsional and tensile actuation. Difference Between Yield Strength and Tensile Strength In materials engineering, yield strength and tensile strength are two properties that can be used to characterize a material. The main difference between yield strength and tensile strength is that yield strength is the minimum stress under which a material deforms permanently , whereas tensile strength describes the maximum stress that a torsional strength tensile strength and make DRILL PIPE PERFORMANCE CHARACTERISTICS SHEET Torsional Strength (ft-lbs) 63,406 Max Recommended Make-up Torque (ft-lbs) 38,044 Min Recommended Make-up Torque (ft-lbs) 28,533 Tensile strength (lbs) 1,551,706 Tool joint/Drill pipe torsional ratio (New pipe) 0.86 Drill pipe assembly with NC50 tool joint Average length (ft) 31.5 Drift size (in) 2.625 Note: Tool Joint and Pipe body values were torsional strength tensile strength and make
As the drill pipe tool joint OD wears the torsional strength decreases. Tool joints with TSRs less then 0.8 are used successfully in low torsion drilling, and some high for torsion drilling applications require tool joint torsional ratings higher than the standard TSR of 0.8. Drill Pipe Make Up Torque Although the torsional yield strength is needed to design the torsional strength tensile strength and make A very rough estimate of the torsional yield strength can be obtained by assuming that the tensile yield strength is between 60 and 90 percent of the tensile strength. Then the distortion-energy theory can be employed to obtain the torsional yield strength (S ys = 0. 577 S y). This approach results in the range 0. 35 S ut S sy 0. A New Method to Test Concrete Tensile and Shear Strength with torsional strength tensile strength and make The torsion test apparatus can be used with any universal testing machine to test concrete or other materials (such as rocks). The apparatus used to apply torsional loads establishes a new method to evaluate concrete tensile strength activating helical tensile failure modes and determining the helical tensile strength (HTS).
