Der biaxiale Kreuzzugversuch zur Ermittlung von Werkstoffkennwerten von Airbaggeweben am Beispiel von Polyamid 6.6

Abstract

The determination of material data on samples under real, complex, test conditions is of considerable interest. In this work a cruciform test for airbag fabric and some exemplarily measurement curves for a typical polyamid 6.6 airbag fabric are presented and discussed

Development of a biaxial tensile device in the plane for monotonic mechanical tests and cruciform specimens / Desenvolvimento de um dispositivo de tração biaxial no plano para ensaios mecânicos monotônicos e de corpos de prova cruciformes

“…TERRIAULT, SETTOUANE and BRAILOVSKI [21] presented a similar device, with the difference that, while the first [20] works with the distance between the two fixation points on the testing machine, the second [21] works with the approximation, simulating a compression test and, in this case, the mechanism is Brazilian Journal of Development, Curitiba, v.7, n.8, p. 86071-86088 aug. 2021 responsible for providing tension in both axes. In the device developed by ROHR, HARWICK and NAHME [22], a remarkable simplification of the number of interconnections was obtained by the use of linear guides. These authors [22] also proposed a modification to perform non-equibiaxial tests by changing the length of the bars on one of the axes.…”

These authors [22] also proposed a modification to perform non-equibiaxial tests by changing the length of the bars on one of the axes. Later, devices similar to this one appeared, such as the one developed by BARROSO et al, [23] and by MARCELO and ANDRÉS [24].…”

Mechanical behavior of airbag fabrics under quasi-static loading: an experimental evaluation of macro- and meso-scopic properties

“…In a subsequent study, Rohr et al 7 carried out biaxial cruciform tests to determine the material behavior under 1:1 biaxial loading. The experimental rig used consisted of four lever arms where one end of a lever is connected to a traditional mechanical tester crosshead while the other ends traveled on a track equipped with piezoelectric sensors to record the pulling load from the fabric specimen.…”
