Popis:	The importance of the process zone (also called the damage zone, plastic zone or active zone) has been recognized since the works of Irwin [1], Orowan [2] and the celebrated models of Dugdale [3] and Barenblatt [4]. Recently, a thermodynamic analysis of the crack and process zone growth as an evolution of one system called the Crack Layer has been advanced [5-9]. The Crack Layer analysis is quite tedious, particularly due to the complexity of the crack tip field resulting from the crack-process zone interaction problem [10]. In the present work the effect of the process zone on the fracture path is analyzed experimentally using a new technique based on controlled exposure of a poly(ethylene-co-carbon monoxide), ECO, to ultraviolet radiation, (UV). UV exposure to ECO results in hardening and embrittlement of the sample [11]. A comparison of the findings in this work with previous studies is also presented [ 12].
