Macro-indentation testing of soft biological materials and assessment of hyper-elastic material models from inverse finite element analysis
Ayyalasomayajula, Venkat Siva Radha Krishna; Ervik, Øyvind; Sorger, Hanne; Skallerud, Bjørn Helge (Peer reviewed; Journal article, 2024)Mechanical characterization of hydrogels and ultra-soft tissues is a challenging task both from an experimental and material parameter estimation perspective because they are much softer than many biological materials, ... -
Microstructure and mechanics of the bovine trachea: Layer specific investigations through SHG imaging and biaxial testing
Ayyalasomayajula, Venkat Siva Radha Krishna; Skallerud, Bjørn Helge (Peer reviewed; Journal article, 2022)The trachea is a complex tissue made up of hyaline cartilage, fibrous tissue, and muscle fibers. Currently, the knowledge of microscopic structural organization of these components and their role in determining the tissue’s ... -
Region- and layer-specific investigations of the human menisci using SHG imaging and biaxial testing
Rasheed, Bismi; Ayyalasomayajula, Venkat Siva Radha Krishna; Schaarschmidt, Ute Alexandra; Vagstad, Terje; Schaathun, Hans Georg (Peer reviewed; Journal article, 2023)In this paper, we examine the region- and layer-specific collagen fiber morphology via second harmonic generation (SHG) in combination with planar biaxial tension testing to suggest a structure-based constitutive model for ...
