Stiffness notched specimen

In order to calculate the fracture properties from the SENS test it Is necessary either to know or derive the stiffness of the specimen and the contact stiffness between the striker and the specimen. For this work the contact stiffness was measured directly by striking a fully supported and un-notched specimen fig 3. Striker force and displacement were measured and used to determine the contact stiffness. Test were conducted at an Impact velocity of 0.5ms, and the contact stiffness was 3.7MPa for the PE, lOMPa for the PMMA and 7.69MPa for the PVC. [Pg.225]
