Cross Type

In this study, dynamic behaviors of cracks under dynamic biaxial stress were investigated. We conducted static and dynamic loading fracture experiments on a magnesium alloy (AZ31B-O) under equitable and inequitable biaxial stress by using a hydraulic high-speed biaxial experimental machine. We processed specimens as the cross type with a crack. Different kinds of cracks were defined by their crack angles. We analyzed the results using the caustic method. The experiments revealed some important findings; there is a negative relation between the fracture toughness value and the plate thickness of the magnesium alloy sheet specimen; the fracture toughness value decreases when the crack has an angle different from the loading direction; the fracture toughness value decreases significantly under inequitable biaxial stress.

In this study, the dynamic behaviors of cracks under dynamic biaxial stress are investigated. We conduct dynamic loading fracture experiments on the aluminum (2024-T3) and the magnesium alloy (AZ31B-O) under equitable biaxial stress with a hydraulic high-speed biaxial experimental machine. The processed specimens are cruciform with a crack. Different kinds of cracks are defined by their crack angles. We analyze the results by the caustic method. We obtained the stress intensity factor and the fracture toughness value in the neighborhood of the crack tip under dynamic biaxial stress. We analyzed the obtained data, and then, we compared results.
