What is the contact area between threads and how does it change?

Webb26 juli 2024 · Don't be confused with Root area - a more conservative stress area that is still widely used such as in ASME B31.1 code. Root area is based on the root or minor diameter of the threads, and therefore its stress area is smaller than the tensile stress area. Root area is not based on experimental data. WebbThe experimentally derived pullout strength was compared to a predicted shear failure force of the internal threads formed in the polyurethane foam. Screws embedded in porous materials pullout by shearing the internal threads in the porous material.
