3D Bulk Analysis of Residual Stress for Better Simulation Tools

1 mars 2024

Synchrotron X-ray diffraction, coupled with our streamlined data analysis software -Scatterin SaaS-, are not just tools; they can speed up and improve how we understand and engineer materials in various industries.

Residual stresses affect the strength, dimensional stability, and fatigue life of a material. Therefore, their quantification becomes relevant in applications such as aerospace components. The distribution of residual stresses also plays an important role in feeding and validating models widely used by industry.


In our recent collaboration with RISE Research Institutes of Sweden Unit of Component Manufacturing and aerospace substructure producer Brogren Industries AB, Scatterin AB employed synchrotron X-ray diffraction (S-XRD) at the P07 High Energy Materials Science Beamline, PETRA III, DESY to quantify 3D bulk residual stress distribution in complex-shaped aerospace engine parts. S-XRD, coupled with our streamlined data analysis software -Scatterin SaaS-, are not just tools; they can speed up and improve how we understand and engineer materials in various industries, in this particular case aerospace industry.


Our Approach:

Traditional stress analysis techniques are incapable of determining full residual strain tensors, probe bulk stress distributions and non-destructively follow their evolution. S-XRD, on the other hand, can penetrate through cm-level thicknesses in components and enable hundreds of measurements within minutes. The high-speed data analysis of large amounts of data using Scatterin SaaS overcomes the challenges posed by the part's complex shape and ensures a rapid turnaround time to get to final results for our partners.


Correlation with Simulations:

One of the important outcomes of our project was the validated correlation between the Finite Element Method (FEM) simulations and the experimental results. The excellent agreement between simulated and experimental results also showcases the reliability and accuracy of the S-XRD technique and Scatterin SaaS. This highlights the potential to use our technology to feed and validate models used in various fields of industry.


Peter Ottosson, expert modelling researcher, from RISE add:

Comparison between physical measurements and simulation results showed promising agreement and thereby it increases the accuracy when modelling manufacturing processes, for example, additive manufacturing and thermomechanical forming to yield results with high fidelity. Thus, this way of combining physical measurement results with modelling contributes to achieving “First-time-right” production.

Cost-Effectiveness and Industrial Viability:

S-XRD offers high measurement rates, allowing stress measurement data to be obtained in seconds. When coupled with the rapid data analysis facilitated by Scatterin SaaS, these techniques become more precise and cost-effective for industrial applications compared to other methods. This makes them highly suitable for both R&D and quality control purposes.

In 2024, Scatterin team looks forward to contributing further to the efficient industrial use of neutron and synchrotron X-ray facilities for rapid and green materials and process innovations.
