Are there any existing experiments for non-axial tensile testing?

Click For Summary
SUMMARY

The discussion focuses on the need for non-axial tensile testing experiments for bolts, particularly when the load is applied at various angles to the bolt's axis. The complexity arises from the bolts being grouted, which complicates the understanding of material properties. Existing literature includes studies by Munse and Cox (1956) and Steeve and Wingate (2012), which explore combined shear and tensile tests but do not specifically address larger-scale non-axial tensile tests for bolts. Participants seek additional resources or experiments that align with their specific testing needs.

PREREQUISITES
  • Understanding of tensile testing principles
  • Familiarity with material properties and their influence on testing outcomes
  • Knowledge of grouting effects on bolt performance
  • Experience with composite material testing methodologies
NEXT STEPS
  • Research non-axial tensile testing methods for bolts
  • Explore combined shear and tensile testing techniques
  • Investigate the effects of grouting on tensile strength
  • Review larger-scale tensile testing experiments in engineering literature
USEFUL FOR

Mechanical engineers, materials scientists, and researchers involved in bolt testing and structural integrity assessments will benefit from this discussion.

Hi guys,

So say I want to perform tensile tests on a bolt, but want to see what the effect of applying the load at various angles to the axis of the bolt would be. It's kindabutnotreally a shear test... I realize that if I had complete knowledge of the material properties of the bolt I could probably figure it out, but it's more complicated than that because the bolt is grouted.

Does anyone know if any kind of intentionally-misaligned tensile test experiment exists? I've found some for composite materials but they consider "non-axial" to mean that the fibres are aligned at an angle to the test axis and generally examine small samples.

Thanks.

Found some stuff on combined shear/tensile tests for the people of the far future who see this post:
Munse and (I love this name) Hugh Cox, 1956:

Steeve and Wingate (NASA), 2012:

Any further info would be appreciated, especially larger-scale experiments.
