  • Torsion testing devices and methods
    Patent number: 10408724
    Abstract: A torsional testing device for testing helical tensile strength, shear strength, and interface bond shear strength using an apparatus to apply torsional loads on a cylindrical specimen is provided. A plurality of slings is wrapped in opposed circular directions around the specimen. A connecting bar is coupled to a first end of each of the slings. A second end of each of the slings is coupled to a frame. A conventional compression load testing machine applies a compressive load to the connecting member causing the slings to apply rotational forces to the specimen in opposite senses creating torsional stresses. Rotational forces are transmitted to the cylindrical specimen due to friction between the slings and the surface of the specimen being tested. The amount of force applied to the specimen is measured so that the torsional strength of different specimens can be compared.
