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 ...

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.

Shape optimisation of a biaxially loaded cruciform specimen
Polymer Testing, 2010 In the present study, the shape of a cruciform type specimen under biaxial loading conditions is optimised. The basic goal is to achieve uniform biaxial failure in the centre of the specimen and minimise undesirable phenomena, such as premature failure outside the area of interest and non uniformities on the central strain field, caused by stress ...

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.

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.

Optimization Design of a Small-Sized Cruciform Specimen for Biaxial Fatigue Testing
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.
