Use the following calculator to convert yield or tensile values in ksi, Mpa, N/mm or psi. The ultimate tensile strength is the maximum on the engineering stress-strain curve. Phone: 800.599.6926Email: anthony@portlandbolt.com. The applied tensile stress in a body is defined as the sum of the internal forces per unit area of the object. For an M6 and M8 bolt I need to determine the bolt length to withstand certain applied forces. Proofload values should be published in the appropriate ASTM standard, or can be calculated from yield. You want the bar to be able to bend (so you can still pick it up), but not bend permanently. For an example, lets use normal draft. In this regard, I am deciding to use square pipe 150x75x6.3mm to hold the load coming over this projected structure by bolting pipes on concrete slab to avoid the distressing of structure in place. It depends only on the maximum force and cross-section area. @Don Using the area (3.14 x r^2) and multiplying that by the approximate shear strength (60% of tensile), I get the following values: 3/4=31,824lbs. WebTensile strength from Brinell hardness can be roughly estimated by multiplying 3.45 and Brinell hardness and is represented as TS = (3.45/9.8067)*HB or Tensile Strength = (3.45/9.8067)*Brinell Hardness.

I need to do a verification calculation to show that using 10 bolts in a 20 bolt ANSI 900 flange with a garlock gasket operating at 700 psig is safe. 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. In addition, I have calculated the load coming on to this projected portion but I am not sure how to design the number of bolts and dia bolts to counter act the load on the projected portion. Ultimate shear strength is commonly estimated to be 0.6*UTS. This restoring force is in general proportional to the stretch described by Hooke's Law. @Erinosho There are conversion charts available to convert hardness to tensile for steel and steel alloy products, but I do not know if they are accurate for Titanium alloys. The top of of your beam, loaded in compression, will fail in buckling. Normally, the proof load values are about 90-92% of yield,but that can vary. a) the tensile strength, also known as the ultimate tensile strength, is the load at failure divided by the original cross sectional area in which the ultimate tensile strength (U.T.S.) This will be L.. Finally, we divide the stress by strain to find the Youngs modulus of steel: E = / = 300*10 / 0.0015 = 200*10 = 200 GPa . could you give me an estimated weight just for comfort is it atleast 5000 lbs per bolt. @Ravish Yes it is possible, but not common, that a bolt can pass the tensile test but fail the proof load test. Web2) tensile strength of steel is higher than compressive strength, steel experience good behave in tension whereas poor behave in compression. This limit is achieved by electric and magnetic field lines, QCD flux tubes, and the fundamental strings hypothesized by string theory. Thanks in advance. hi.
