Design optimization of cruciform specimens for biaxial fatigue loading [PDF]
Fracture and Structural Integrity, 2014 In order to correctly assess the biaxial fatigue material properties one must experimentally test different load conditions and stress levels. With the rise of new in-plane biaxial fatigue testing machines, using smaller and more efficient electrical ...

Steel Cruciform Sample with Nitrided Arms Achieves Higher Plastic Strain in the Gauge Region
Applied Sciences, 2022 This paper describes a novel solution to increase plastic strain in the gauge region of a cruciform sample during a forming limit test. A nitriding procedure was used to increase the strength of the arms of the specimen and at the same time enabled ...
