Abstract

Automotive component manufacturers are under pressure to give reliability over widening ranges of operating temperature. Japanese motor manufacturers require their vehicle components to function between temperatures of -45°C and 120°C. The previous limits were -40^C and 100°C. The new limits create difficulties for producers of numerous components, but none more so than those making rubber parts. It is far more difficult to characterise material behaviour for rubbers than for linear elastic materials. Though finite element analysis of hyperelastic materials has gained greater acceptance recently, sensible modelling of parts subjected to high, localised deformations is still uncertain. There is no universal model for the ch
