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 ...

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 ...

Science and Engineering of Composite Materials, 2021 Characterization of shear behavior in composite materials remains a not fully solved problem. In the last fifty years, many different approaches have been proposed to solve this problem (rail shear, thin-walled tube torsion, off-axis tensile, ±45 ...

Design of Cruciform Specimens for Biaxial testing of Composites [PDF]
Advanced Composites Letters, 1992 Orthotropic finite element analysis was used to design a cruciform specimen for use in biaxial testing of fiber reinforced composites. Several notch designs were investigated and the optimal specimen shape was chosen as the one in which failure would more likely occur in the gage section rather than across the cruciform arms.
