PERFORMANCE OF FOUR PLASTICS IN RELATION TO BOLT RELAXATION IN A NON-CONDUCTING RAIL JOINT

Experiments have been conducted to observe the relaxation behavior of fishplate-bolted rail joints in which four different polymeric materials were used for electrical insulation. Static tests were conducted to study the effect of temperature and of different locking sequences for the bolts on a rig which simulated service conditions at a joint. The effect of cyclic loading was considered.
