WebAn approximate relationship between the hardness and the tensile strength (of steel) is, where HB is the Brinnell Hardness of the material, as measured with a standard indenter and a 3000 kgf load. If nut and bolt are made from the same material,and thread engagement is at least 55% the bolt will pull into (tensil) before the thread shears. TVP (Materials) 20 May 06 13:40. If the grading is 8.8, with reference to the first number 8, this means the ultimate tensile strength (breaking strain to be at least this) is 800MPa, or, 800N/mm. Measure its initial length, L without any stress applied to the material. For example do you need its tensile value, or shear value, or perhaps some other value? Once the tensile capacity (or strength) of the material is assessed, engineers will typically calculate the applied stress in the component. Specifically 35mm diameter 3mm thick 1000 mm long. Bending strength and Tensile Strength relation In the formula of torque value calculation there is mention clamp load= 75 % of proof load. The 0.57*TYS is probably taken from the von Mises/distortion energy/octahedral shear stress criterion, and it should be stated as shear yield strength = 0.577*tensile yield strength. Mechanical Testing - Tensile Testing Part Below is a simple metal strength chart you can use to compare metals: Types of Metals. The breaking point is the tensile stress area multiplied by the minimum tensile in psi. Ultimate shear strength is commonly estimated to be 0.6*UTS. ), max = P max /A 0 , where P max = maximum load, A 0 = original cross sectional area. The self drilling screw based on SCREW #8 x 1/2(P/H). Continuing with the example from Step 1, multiplying five by six equals an area of 30 square inches. 1=56,520lbs.
