Pagination or Media Count:
This experimental study investigates the fatigue crack growth rate behavior of an epoxy resin polymer using the tapered-double-cantilever-beam TDCB specimen in ambient and elevated temperature environments. An empirical crack growth rate model based on the change in crack extension force, delta G, is proposed. Its relation to delta K models is discussed and observations on the fatigue surface morphology presented.
