WebbUSS: Ultimate Shear Strength, UTS: Ultimate Tensile Strength, SYS: Shear Yield Stress, TYS: Tensile Yield Stress There are no published standard values for shear strength like with tensile and yield strength. Instead, it is common for it to be estimated as 60% of the ultimate tensile strength. The stress-displacement, or vs x, relationship during fracture can be approximated by a sine curve, , up to /4. The initial slope of the vs x curve can be related to Young's modulus through the following relationship: where • is the stress applied.
