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 MSCPSC, INC to fatigue modeling of elastomers and incorporate microstructure.
