AbstractLocal Strain Energy Density represents an engineering approach for assessing the brittle fracture of cracked and notched components. Experimental determination of fracture parameters (critical value of deformation energy Wc in a local finite volume around the notch tip and the radius of the control volume Rc) represents a key issue. The paper presents a methodology to determine these parameters using a notched tensile specimen. The obtained values will be used to predict the fracture for different types of notches and cracked specimens under mode I; for cracked specimens under mixed mode and mode II has proposed a new approach which confirms that PUR foams can be treated as brittle materials. The considered specimens are made of rig...
