Kambour model, crazing

Using a modified Dugdale model with a variable craze stress along the craze zone this effect has quahtatively been interpreted At positions where the constant stress Dugdale model gives displacements higher than the measured ones the actual craze stress must be higher. In the case of PC a closer inspection reveals a stress peak at the crack and craze tip. Kambour predicted just such a stress distribution in a craze from the analysis of the stress distribution around a craze (without a crack)... 

We can further explain the temperature rise, in terms of the model in which a craze forms at the tip of a crack in a glassy polymer under stress, and advances ahead of it. (The extensive work of Kambour and others, in the last decade or so, has elucidated the...
