Explore our group’s latest publication in Acta Materialia, led by Dhruv Anjaria. Our research focuses on the plasticity of a FCC material at cryogenic temperatures (liquid nitrogen and helium temperatures). We discovered a novel deformation mechanism where deformation twinning and slip compete, causing the delocalization of plastic deformation, which impacts the properties of metallic materials …
Check out our latest publication in Acta Materialia: https://lnkd.in/gNftY7e6 Utilizing high-temperature, high-resolution digital image correlation, we’ve been able to observe the temperature-dependence of plastic localization at the nanoscale across a wide field of view. This approach has led to a deeper understanding of the microstructure-dependence of diffusion creep (Coble creep) phenomena during the deformation of …
Our research team has made a breakthrough in understanding the micro-mechanisms that contribute to fatigue damage under tension-tension loading. These findings are detailed in our recent publication in the journal Acta Materialia. The paper, authored by R.L. Black, D. Anjaria, J. Genée, V. Valle, and J. C. Stinville, is titled “Micro-Strain and Cyclic Slip Accumulation …
The Stinville group, in partnership with researchers from UCSB, Mines ParisTech, UIUC, and BAM, has recently published an article in the prestigious ARMR journal. The paper presents groundbreaking research endeavors focused on comprehending the localization of plasticity in metals.

Ph.D. Candidate Rephayah Black demonstrated the used of the Multi-Beam SEM technology to statically measure nm-scale plastic deformation events: High-Throughput High-Resolution Digital Image Correlation Measurements by Multi-Beam SEM Imaging, Experimental mechanics https://doi.org/10.1007/s11340-023-00961-y Background: Recent improvements in spatial resolution and measurement sensitivity for high-resolution digital image correlation (HR-DIC) now provide an avenue for the quantitative measurement …
Ph.D. Candidate Chris Bean investigated plastic localization in AM microstructure: International Journal of Plasticity Volume 159, December 2022, 103436 Additively manufactured 316L stainless steels display significantly higher yield strength than their as-cast or wrought counterparts. This is associated with the micro-scale cellular structure and complex grain and sub-grain structure, resulting from high cooling rates occurring …
Engineers can now capture and predict the strength of metallic materials subjected to cycling loading, or fatigue strength, in a matter of hours – not the months or years it takes using current methods. In a new study, researchers from the University of Illinois Urbana-Champaign report that automated high-resolution electron imaging can capture the nanoscale …
The paper entitled “A Multi-modal Data Merging Framework for Correlative Investigation of Strain Localization in Three Dimensions” has been selected as the JOM Editor’s Choice for November 2021.
