A strong strain-rate and temperature dependence was observed for the fracture toughness of phenolphthalein polyether ketone (PEK-C). Two separate crack-blunting mechanisms have been proposed to account for the fracture-toughness data. The first mechanism involves thermal blunting due to adiabatic he

Uniaxial tension tests to the yield point were performed on phenolphthalein polyether ketone (PEK-C) from room temperature to near the glass transition temperature (T,) at a constant rate of 0.02 min-'. At room temperature, some measurements were also made at strain rates from 0.002 min-' to 2 min-'

The J-integral is applied to characterize the fracture initiation of phenolphthalein polyether ketone (PEK-C ) for which the concepts of linear elastic fracture mechanics (LEFM) are inapplicable at high temperatures for reasonably-sized specimens due to extensive plasticity. The multiple-specimen re
