Optimization Design of a Small-Sized Cruciform Specimen for Biaxial Fatigue Testing [PDF]
Metals, 2020 The in-plane biaxial specimen can well reflect the complex stress state of sheet metal. However, there is no standard for small-sized specimens used in the low-power biaxial fatigue testing machine.

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.

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 ...

Cruciform Specimen Design for Biaxial Tensile Testing of SMC [PDF]
Journal of Composites Science, 2018 This paper presents an investigation of different cruciform specimen designs for the characterization of sheet molding compound (SMC) under biaxial loading. The considered material is a discontinuous glass fiber reinforced thermoset. We define various (material-specific) requirements for an optimal specimen design.

Designing a Cruciform Specimen via Topology and Shape Optimisations under Equal Biaxial Tension Using Elastic Simulations. [PDF]
Materials (Basel), 2022 Stress uniformity within the gauge zone of a cruciform specimen significantly affects materials’ in-plane biaxial mechanical properties in material testing. The stress uniformity depends on the load transmission of the cruciform specimen from the fixtures to the gauge zone.

Effect of cruciform specimen design on strain paths and fracture location in equi-biaxial tension
Journal of Materials Processing Technology, 2021 Abstract Hot stamping technologies require new methods for evaluating formability of sheet metal under various forming conditions. Biaxial tensile testing method using a cruciform specimen has been used for the applications, but a suitable cruciform specimen design has not yet been accepted.

Procedia Structural Integrity, 2017 Abstract Nowadays the development of new testing machines and the optimization of new specimen geometries are two very demanding activities. In order to study complex material stress and strain distributions, as in-plane biaxial loading, one must develop new technical solutions. A new type of testing machine has been developed by the present authors,

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.
