Screw stress area
WebbIt is not applicable to set screws and similar threaded fasteners not under tensile stress (see ISO 898-5). It does not specify requirements for such properties as weldability, corrosion resistance resistance to shear stress, torque/clamp force performance (for test method, see ISO 16047), or fatigue resistance. General information Status Webbby the area at the pitch line. The direction of the net load is parallel to the pitch line and in the analysis this component of the force will be unity. The radial stress (_r) and axial stress (_a) are normalized to the shear transfer rate. The above discussion relates to a normal screw thread problem where only

Webb$\begingroup$ Failure for shear in the plastic would occur at the perimeter of the washer, so if it's 2" square, your area resisting shear would be the perimeter times the thickness (8" * 1/8" = 1 Square Inch.) If the nut if more than snug tight, the preload will add some shear stress before there is any uplift on the plastic sheet.I'm sure someone who knows about … WebbTensile/Compressive stress in the screw core. 2.12 Equivalent stress. In case of simultaneous action of tensile stress / pressure and torsion, it is necessary to deal with combined stress and loads. The reduced stress should be less than the allowed tensile stress. 2.13 Safety coefficient . It is related to the equivalent stress. 2.14 Buckling ...
