Elastic-plastic Contact of a Deformable Sphere Against a Rigid Flat for Varying Material Properties Under Full Stick Contact Condition
Journal Title: Tribology in Industry - Year 2011, Vol 33, Issue 4
Abstract
The present study considers finite element based contact analysis of an elastic-plastic axisymmetric hemisphere using ANSYS to study the effect of material properties under full stick contact condition. Results are compared with previous elastic-plastic models for perfect slip and full stick contact conditions. It is found that materials with modulus of elasticity to yield strength (E/Y) ratio less than and greater than 300 show strikingly different contact behavior. When E/Y ratio is less than 300, contact load increases with the increase in modulus of elasticity whereas in elastic-plastic range, contact load decreases with the increase in yield strength.
