Durability Testing of Tank Track Rubber Compounds under Cyclic Loading

The mechanical durability of three tank track rubber compounds, designated as 15TP-14AX 15NAT-25A and 15TP-R were evaluated within the framework of cycle shifted failure envelop (CSFE) model for rupture of carbon black filled rubbers. It was found that, while the CSFE model is imperfect, it serves a...

Description
Summary:The mechanical durability of three tank track rubber compounds, designated as 15TP-14AX 15NAT-25A and 15TP-R were evaluated within the framework of cycle shifted failure envelop (CSFE) model for rupture of carbon black filled rubbers. It was found that, while the CSFE model is imperfect, it serves as a useful framework for evaluating the mechanical durability of the rubber compounds. The three rubber compounds could be ranked for durability in creep and in zero tensile sinusoidal fatigue. The results show that the ranking varies with test conditions, e.g., temperature, test frequency, etc. New results are presented showing violation of the classical failure envelope model.
