An online calculator for estimating the Hertzian Stress for two bodies in contact.
10 Μαρ 2021 · The resulting stress in the contact patch is called contact stress or Hertzian Stress. The contact stress in this small contact patch (either ellipse or rectangle) is repeated at the frequency of rotation.
8 Οκτ 2023 · Formula: The Hertzian Stress (σ) at the center of contact can be calculated using the formula: σ = (P / πab) * ((1 – ν₁²) / E₁ + (1 – ν₂²) / E₂)^(-1/2) Variables
The contact are is assumed to be small relative to the overall dimensions of the contacting bodies. The applied load is purely normal to the surfaces in contact. The material is homogeneous.
No frictional forces within the contact area. An online calculator for estimating the Hertzian Stress for a cylinder in contact with a flat surface or a flat plate.
A list of online Hertzian contact stress calculators created by Precision Mindset PLLC.
In mechanical engineering and tribology, Hertzian contact stress is a description of the stress within mating parts. This kind of stress may not be significant most of the time, but may cause serious problems if not take it into account in some cases.
