RISBiaxial Tension of Fibrous Tissue: Using Finite Element Methods to Address Experimental Challenges Arising From Boundary Conditions and Anisotropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Planar biaxial tension remains a critical loading modality for fibrous soft tissue and is widely used to characterize tissue mechanical response, evaluate treatments, develop constitutive formulas, and obtain material ...
Internal Three Dimensional Strains in Human Intervertebral Discs Under Axial Compression Quantified Noninvasively by Magnetic Resonance Imaging and Image Registration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Study objectives were to develop, validate, and apply a method to measure threedimensional (3D) internal strains in intact human discs under axial compression. A custombuilt loading device applied compression and permitted ...
Human Disc Nucleotomy Alters Annulus Fibrosus Mechanics at Both Reference and Compressed Loads
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Nucleotomy is a common surgical procedure and is also performed in ex vivo mechanical testing to model decreased nucleus pulposus (NP) pressurization that occurs with degeneration. Here, we implement novel and noninvasive ...
