UPON FINITE LENGTH LINE CONTACTS BETWEEN NONLINEAR ELASTIC BODIES

Ionut Romanu

Abstract


The paper reveal some studies conducted on infinite length line contacts between nonlinear elastic bodies and proposes several applications for the study of finite length line contacts between such bodies. The determined numerical values for contact half-width and maximum contact pressure at different load levels are graphically represented and then compared with ones obtained for the case of elastic bodies in contact. Evolution of contact half-width and maximum pressure with load are presented too.

Keywords


line contact, nonlinear elasticity, linear elasticity, pressure distribution, end effect
