How To Calculate Elongation Of Steel @Ravish Yes it is possible, but not common, that a bolt can pass the tensile test but fail the proof load test. 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. @Abdul I am sorry, but we are unfamiliar with those international standards, so cannot comment on them. The field can move in the axial direction some which is why Id like to bolt the two tares together. If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords. Convert Approx. My question is what size bolts would I need to be able to support the stress of the field moving in the axial direction?

Continuing with the example from Step 1, multiplying five by six equals an area of 30 square inches. @Chris- You are correct, I should have qualified that if the bolt is improperly designed or installed, it could strip. Strain (normal) A measure of the deformation of the material that is dimensionless. I have seen literature that suggests a FoS of 8.5, although in engineering, FoSs of 2 5 are more common. Does strength of an all thread change if you band saw/ cut to a shorter length. This formula will give you the ultimate yield strength of that size and grade of bolt. Once the tensile capacity (or strength) of the material is assessed, engineers will typically calculate the applied stress in the component. Tensile strength is important on the bottom of your beam. width (w) = 0.505 in. I cannot account for any loads on the bent portion, just the straight round bar. If your structure is rigid enough that it does not wobble about, it will be very strong.
