A machine learning-based constitutive model is proposed to capture the strain rate-dependent, nonlinear stress-strain response of soft tissues. The total stress in the general functional form of this model is additively decomposed into a volumetric, an isochoric hyperelastic, and a viscous overstress component. Each…
Many biological materials, including the extracellular matrix, connective tissue, blood vessels and various membranes have a network of collagen/elastin fibers as their main structural constituent and are classified as Network materials. The accumulation of damage and rupture in these materials leads to pain and…
The possibility of life surviving after a major impact is crucial for solar system missions with possible sample return, since impact is a dominant process in the solar system – how likely is it that the sample contains life? The related question is that…
The lungs are susceptible to injury resulting from behind armour blunt trauma (BABT). In this scenario, the deformation of the backface of the armour system impinges on the thoracic wall leading to elevated strain levels in the lungs. Within this context, the deformation of…
Deformable headforms can be used to make direct in situ intracranial strain measurements, however these physical models require significant refinement to ensure biofidelity. In particular, the boundary conditions of the brain-skull interface will influence the intracranial displacements and strains that develop due to a…
During training and operations, pilots endure high-magnitude repetitive loads that could cause acceleration of deterioration of the discs in the spine. Disc degeneration occurs when high stresses wear down the intervertebral discs in the spine, which can cause neck and back pain. Research is…
