Contact Stress Simulators

Compute the elliptical contact patch of general Hertzian contact: major semi-axis a, minor semi-axis b and peak pressure p_max from normal load and principal curvatures.

Calculate Hertz contact pressure, radius, and deflection for spheres, cylinders, or flat geometries. Input materials and load for instant results.

DMT Adhesive Contact Simulator for hard elastic spheres: predict pull-off force and contact area using Derjaguin-Muller-Toporov theory and Tabor parameter validation.

Interactive Hertz contact stress calculator for sphere-sphere, sphere-flat, and cylinder contacts. Visualize contact pressure distribution and subsurface stress in real time.

Hertz Line Contact Simulator for parallel cylinders: analyze contact pressure and half-width in roller bearings, cams, gears. Adjust load, radii, modulus.

JKR (Johnson-Kendall-Roberts) adhesive contact simulator for soft elastic spheres. Real-time contact radius and pull-off force from surface energy, modulus, radius and load.

Calculate rolling contact stress using Hertz theory. Input geometry, materials, and load to get contact radius, peak pressure, and subsurface shear stress.

Hertz subsurface stress simulator. Compute centerline σz, σr and τmax under a Hertzian sphere contact in real time; peak shear at z≈0.48a is the pitting origin.

Wheel-rail contact simulator for Hertz elliptical contact analysis. Adjust load, radius, friction to calculate contact pressure and adhesion limits.
