Abstract:

This paper presents some considerations regarding dynamic stress intensity factor determination using a three point’s bends analytical method. This method is based on a double mass-spring system. In this system the specimen and the striker are both represented as mass-spring system. The specimen stiffness is computed using the midspan deflection of the beam and the contact stiffness is computed using a linear force-deformation relation.

Keywords:

dynamic stress intensity factor, contact stiffness, impact test, midspan deflection, three point bend test.
