Abstract
A recent development on identifying the static and dynamic initiation fracture toughness of materials by using a single v-notch spiral crack is presented. A polycarbonate solid cylindrical sample with spiral crack is implemented in this work to demonstrate the method. The quasi-static experiment was conducted by applying a pure torsion on the specimen using an MTS axial-torsion machine. The dynamic fracture experiment was conducted using Torsional Spilt Hopkinson Bar. In both cases, the torque corresponding to fracture initiation is measured experimentally and used as input to the numerical simulation. A new emphasis relation for a cylindrical specimen with spiral crack is also proposed and used with the experimental data to quantify the initiation fracture toughness. The results show that the spiral crack specimen is an effective method to determine the fracture toughness of materials.
