  Image-Based Quantitative Mapping of Structure Property Relationships in Polymer Composite Materials

  By Mohandass G., B. Ram Priya, R. Arangasamy, C. Sridhathan

  Abstract: The performance of polymer composite materials is intrinsically governed by their microstructural architecture, which is shaped by manufacturing conditions and constituent interactions. Despite extensive experimental characterization efforts, establishing transparent and quantitative structure–property relationships from microstructural images remains a challenge. In this study, an explainable image-driven framework is developed to systematically correlate microstructural features with composite property indicators. Microstructure images are processed to identify voids, fibers, and filler phases, from which …

  Non-Contact Quantification of Swelling-Induced Deformation in Polymer Hydrogels Using Image Analysis

  By R. Arangasamy, C. Sridhathan, Mohandass G., B. Ram Priya, N.M.G. Kumar, D. Harika

  Abstract: Swelling of polymer hydrogels governs transport, mechanics, and functional performance in biomedical systems, yet it is often reported using bulk ratios that conceal spatially heterogeneous deformation and boundary-driven instabilities. This study presents a non-contact image-analysis framework to quantify swelling-induced deformation by tracking shape and boundary evolution from time-lapse imaging. The approach segments the hydrogel region, extracts a sub-pixel refined contour, and computes boundary displacement descriptors including mean and upper-percentile normal …
