Abstract
Experimental determination of the intrinsic material property data, that requires geometry-independence of the data, is discussed. Analysis of experimental data points from literature and our own experiments yields a general relation between J-integral values and size criterion. Using this relation, it is possible to carry out a material specific estimation of the requirements on specimen geometry of polymers within the entire toughness region.
