On the Intrinsic Fracture Pressure of Liquid and Solid Aluminum Around Its Melting Temperature

To determine the intrinsic fracture pressure of aluminum, data from studies that have used molecular dynamic simulations, the van der Waals method as well as experimental observations have been gathered and analyzed. Results indicate that aluminum has an intrinsic fracture pressure of − 4 GPa at its melting temperature in both liquid and solid states. Moreover, the Fisher equation can be used to estimate the intrinsic fracture pressure of liquid aluminum
