Hertzian stress (subsurface) calculator – Line Contact
This is a Hertzian stress calculator for subsurface stress components in case of a contact between cylinders (line contact). Equations and the references are given below the calculator.
As shown in the figure, a contact of two cylinders is considered here. Hertzian subsurface stresses can be obtained using following equations:
where is the stress component in x direction, is the maximum Hertzian pressure and is Hertzian contact radius.Please find all the related equations here. Corresponding Matlab code for Hertzian solution can be found here. The online Hertzian contact stress calculator can be found here.
