To understand the durability of rubber compound, HASETRI offers prediction of Crack nucleation and crack growth rate at different operating condition.
Fatigue crack growth (FCG) behaviour of elastomer compounds is an essential criterion to understand the cause of failure. As tyre undergoes millions of fatigue cycles during their service life, one micro-crack can lead to an ultimate failure if FCG characteristic of that compound is not sufficient enough to restrict the propagation. There are various factors which influence the FCG characteristics of rubber vulcanizates viz. temperature, strain rate, type of elastomer and filler etc.
It is possible to measure FCG at different environmental conditions:
