Fatigue Analysis - Research Highlights #3 🥼
The third piece of research we would like to highlight in our BND Research Highlights series is a piece of work performed in collaboration with researchers in Professor David Knowles’s group at the University of Bristol and published in the International Journal of Fatigue in 2019 (https://www.sciencedirect.com/science/article/abs/pii/S0142112319301860). This work analysed fatigue microcrack initiation and growth in a stainless steel sample on a custom 3-point bend rig, designed to fit within our Dynamic-SPMs.
How did our SPM enable the best quality measurements?
đź“Ź Our SPMs are capable of measuring picometre-scale height changes. This capability enabled detailed study of slip banding down to single atomic steps (a length referred to as a Burgers Vector).
🚀 High-throughput enabled high-resolution measurements across large areas on the sample for better understanding of high- and low-stress regions on the surface – we typically image at 2 frames per second.
🗺️ Our software enabled stitching of individual frames across a region of interest, producing a final large-area image without sacrificing resolution – the image explored in the video below is XXX pixels for detailed analysis of the surface across XXX um
