Design of a cruciform biaxial tensile specimen for limit strain analysis by FEM
Journal of Materials Processing Technology, 2002Abstract This paper is focused on a study of the sheet forming limit under complex strain loading paths. A cruciform biaxial tensile specimen with a chamfer on the arms and the central region is optimized by FEM simulation in order to realize the complex loading and the limit-strain states of sheet metals in the cruciform biaxial tensile test.

Cruciform Specimen Machining Using EDM and a New Design Verification for Biaxial Testing
Journal of Materials Engineering and Performance, 2020Cruciform flat specimen is mostly used to investigate experimentally the in-plane biaxial mechanical behavior of sheet metals. In this study, a modified cruciform specimen design is proposed and validated against the performance of current standard design.

Design of a cruciform specimen for biaxial testing of fibre reinforced composite laminates
Composites Science and Technology, 2006To study the behaviour of fibre reinforced composite laminates under static and cyclic in-plane complex stress states, a biaxial loading frame has been developed. A cruciform type specimen is biaxially loaded in its plane using four independent servo-hydraulic actuators.

Optimal design of biaxial tensile cruciform specimens
Journal of the Mechanics and Physics of Solids, 1993Abstract F or experimental investigations concerning the mechanical behaviour under biaxial stress states of rolled sheet metals, mostly cruciform flat specimens are used. By means of empirical methods, different specimen geometries have been proposed in the literature. In order to evaluate the suitability of a specimen design, a mathematically well

Design of a biaxial extensometer for measuring strains in cruciform specimens
Experimental Mechanics, 1992A biaxial extensometer for measuring strains in flat cruciform specimens is presented. This extensometer allows for the use of two displacement or strain transducers to control and measure strains along mutually orthogonal directions in the plane of the specimen.

Cruciform specimen design and validation for constitutive identification of sheet metal
AIP Conference Proceedings, 2013Accurate material models are imperative for successful simulations of sheet metal forming. Calibrating these models can benefit significantly from biaxial experimental data, for example by testing cruciform specimens under biaxial tension. While this technique allows for significant flexibility in the strain paths that can be investigated, a major ...

Numerical and Experimental Design of a Cruciform Specimen for a Novel Cryobiaxial Experiment
American Society for Composites 2017, 2017This study presents a combined numerical and experimental attempt to develop a new cruciform geometry for cryobiaxial loading. Two candidate cruciform specimens with crossply stacking sequences are evaluated at room temperature based on their ability to initiate and evolve intralaminar damage in the gage region.
