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 ...

Multi-axial fatigue numerical crack propagations in cruciform specimens
Fracture and Structural Integrity, 2019 Two cracks, initiated from the opposite tips of a central notch inclined by 45䒰, were considered in cruciform specimens made of Ti6246. A static load was applied to a cruciform arm while a cyclic load was applied along the other arm.

Investigation of Biaxial Properties of CFRP with the Novel-Designed Cruciform Specimens. [PDF]
Materials (Basel), 2022 The biaxial loading properties of carbon-fiber-reinforced polymer (CFRP) are critical for evaluating the performance of composite structures under the complex stress state. There are currently no standardized specimens for the CFRP biaxial experiments.

Cruciform specimens' experimental analysis in ultrasonic fatigue testing [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2019 AbstractIn this paper, two special aluminium cruciform specimens are designed and tested in an ultrasonic fatigue machine. They were designed based on Single‐Input‐Multiple‐Output (SIMO) modal analysis to induce in‐plane biaxial stress combinations (in‐phase tension‐tension [T‐T] and out‐of‐phase compression‐tension [C‐T]) when at resonance at 20 kHz ...

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 ...
