Polymethyl methacrylate fracture surface energy

IV. PAKAMETERS AFFECTING EFFECTIVE FRACTURE SURFACE ENERGY, AND FRACTURE TOUGHNESS OF POLYMETHYL METHACRYLATE... [Pg.535]

In the following sections, we shall discuss the effects of molecular weight, crack speed and molecular orientation on effective fracture surface energy, fracture energy and fracture toughness of glassy polymers. Polymethyl methacrylate will be used for illustration. Other variables, e.g., temperature, sampl thickness, etc., have been well discussed in the literature, we do not include them in this section.
