Fracture Mechanics - Applet for an Elliptical Crack

For the configuration above the critical stress is given by a complex expression which is evaluated by the applet below. The lengths should be entered in mm and the fracture toughness in MPa(m)^0.5

Put appropriate values into the spaces and click on 'Calculate'.
