Abstract

The dynamic fracture surface formation of PMMA and epoxy was studied. Fracture parameters such as crack velocity a and crack extension resistance R∗ were obtained by high-speed photography of fracture caustic images. The density of surface marking was also obtained by examination of the fracture surfaces. Correlations between the density,μ and the fracture parameters have shown that, although μ depends on a or on R∗, μ is not a unique function of one of those parameters. It is found that μ has the best correlation with the product R∗-d, i. e. dissipated energy per unit crack front and unit time.
