  Quantitative Image-Based Assessment of Degradation Patterns in Polymer-Based Medical Implants

  By T. Suguna, G. Umashankar, B. Rampriya, M. Rajesh Kumar, P. Venkatesh, T Venkatakrishnamoorthy

  Abstract: Polymer-based medical devices are widely used in clinical practice, where long-term material degradation can compromise performance and patient safety. Traditional polymer degradation studies predominantly rely on laboratory-based experiments, which often fail to capture real-world operational and usage conditions. In this study, a multimodal, data-driven framework is proposed for the quantitative assessment of degradation patterns in polymer-based medical devices using publicly available clinical failure data. Structured operational parameters, including cumulative usage …

  Fibre Orientation and Void Distribution Analysis in Polymer Composite Structures Using Image Processing

  By T. Suguna, G. Reddy Hemantha, Edwin Paul N.E., K. Jayasakthi, M. Dharani, Venkata Prasanth B.

  Abstract: Fibre orientation and void distribution are critical microstructural features that govern the mechanical performance and reliability of polymer composite materials. Accurate and simultaneous characterisation of these features remains challenging due to their complex spatial interactions and dependence on processing conditions. In this work, an integrated image-processing framework is proposed for the quantitative analysis of fiber orientation and void distribution in polymer composite structures. High-resolution composite microstructure images are processed through …
