CALCULATORS / MECHANICAL

Fasteners and joints

Explicit load paths, preload uncertainty and joint stiffness.

bolt diameter, tightening torque, nut-factor interval → preload range, torque sensitivity

axial load, thread stress area, preload → tensile stress, utilization screening

transverse load, bolt group, plate thickness → bolt shear, plate bearing stress

bolt coordinates, force, applied moment → individual bolt loads

preload, external load, bolt/joint stiffness → remaining clamp load, separation threshold

thread geometry, material strengths, load → engagement length, stripping screening

load, bond geometry, allowable stress assumption → required area, average shear or peel indicator

weld geometry, forces and moments, selected allowable → nominal weld stress, required throat

rivet count, diameter, plate thickness, load → rivet shear, bearing, net-section stress

gasket area, seating stress, pressure, bolt pattern → seating force, retained compression demand
