New Test Method for Additive Manufacturing Non-destructive testing and evaluation of fatigue cracks using tensioned computed tomography

1. Scope

This test method covers the use of in-situ tensioning to improve the detectability of cracks in additively manufactured hollow rod fatigue sample using X-ray Computed tomography. This is a non-destructive test performed using industrial x-ray computed tomography and a cost-effective tensioning system. This test method does not cover quantitative sizing of cracks or automated detection of cracks.


Structure Integrity; Damage Tolerance


The fatigue performance of additively manufactured parts must be well understood for the safe use of additive components in service. This standard provides a non-destructively method of studying crack formation and crack growth and increase our understanding of fatigue properties. Expected users include materials development, structural integrity, and research development.

The title and scope are in draft form and are under development within this ASTM Committee.
