Mechanical Behavior and Fatigue Studies of Rubber Components in Army Tracked Vehicles

Abstract

Overview of report: Monotonic approach: Internal state variable (ISV) model for metals; ISV modeling strategy moved to glassy polymers and current efforts to apply ISV modeling strategy to elastomers. Fatigue approach: Researchers have historically separated fatigue crack initiation and propagation, (McDowell et al., 2003) refined the earlier crack stages into incubation and microstructurally and physically small crack growth, greatly increasing accuracy. Microstructure has been incorporated into the multistage modeling for metals at CAVS. Researchers have typically only investigated long crack for elastomers. Current efforts are to add MSC/PSC, INC to fatigue modeling of elastomers and incorporate microstructure.
