School of Dentistry, University of Missouri Kansas City Kansas City, Missouri USA. Tear strength is a measure of the resistance of a material to tearing forces. Strength of the sutures depends on many factors such as tensile strength, compressive strength, and knot configuration. Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or within equations, is the maximum stress that a material can withstand while being stretched or pulled before breaking.
