Package of 3 Apps to calculate: - the torsional stress in one Shaft (solid or hollow), - the life of one component given the stress range with the S-N diagram approach- the stress and clamp load in a ISO screw connected with a plate

Screws & Shaft Stress & Life alternatives

ISO Screws Basic Calculator

This App is not a professional Software, but provide you a Basic Calculation for the ISO screw connections. Starting from the dimensions of the screws and the mechanical & physical properties of the connection, this App calculates simultaneously all the most important parameters usually considered for the stability of the Screw connection. Inputs:Material Ultimate Stress [u]Material Yield Stress [y]Material Maximum Compression Stress [c]Material Youngs Modulus [E]Bolt Head Plate Friction CoefficientBolt Thread Plate Friction CoefficientScrews Nominal & Head DiametersScrews Length & Hole DepthExternal Axial Load and Torque Outputs:Axial Force on the ScrewCompression Force On PlatesMaximum Possible Transverse Load Total Stress On ScrewStress on ThreadScrew Head Contact Pressure

Shaft Torsional Stress Calculator

This App calculates the Torsional Stress, the Maximum Strain and the Safety Factor of the Shaft in function of the geometrical dimensions, the material properties and the applied Torque. Both the inputs data and the output data are in Metric and U.S. Units.

Fatigue Life Calculation S-N Curve

This App calculates the life (expressed as number of Cycles with probability B50) and the Damage caused by a stress Cycle. Input data:1. Life Target for the component [B50] - Optional -As default value, the S-N Diagram assume 0.9 of the Ultimate Stress for the limit of 1,000 cycles [B50] and 0.45 of the Ultimate Stress for the limit of 1,000,000 cycles [B50], but these values can be freely modified.
