On the Applicability of the Schwalbe's Model to the Fracture Toughness Calculation in 7075 Aluminum Alloys

On the Applicability of the Schwalbe's Model to the Fracture Toughness Calculation in 7075... Four 7075-T651 aluminum alloys have been tested in tension in order to assess the applicability of the Schwalbe's model to the fracture toughness calculation. Standard K IC tests were performed on compact tension samples at room temperature, and the results compared with those from the Schwalbe's model which takes into account several mechanical properties derived from a conventional tensile test applied on round unnotched tensile samples, and the average dimple size of the corresponding fracture surfaces. The values of K IC calculated through the Schwalbe's model, correlate qualitatively well with those from the standard technique. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Performance Materials Springer Journals

Abstract

Four 7075-T651 aluminum alloys have been tested in tension in order to assess the applicability of the Schwalbe's model to the fracture toughness calculation. Standard K IC tests were performed on compact tension samples at room temperature, and the results compared with those from the Schwalbe's model which takes into account several mechanical properties derived from a conventional tensile test applied on round unnotched tensile samples, and the average dimple size of the corresponding fracture surfaces. The values of K IC calculated through the Schwalbe's model, correlate qualitatively well with those from the standard technique.
