STRENGTH AND BIOGRAPHY SUMMARY FATIGUE One

surrounding the shear stud is represented by the portion of the equation to the left of the equality, while the portion to the right represents the resistance of a shear stud. Because the shear stud resistance is written in terms of its tensile strength, it implies that a shear stud behaves in pure tension rather than shear, which seems unlikely.
