SUMMARY:Modelling tendon and ligament non-linear elasticity - Tom Shearer

DESCRIPTION:Tendons are the connective tissues that attach muscles to bone
 s. Ligaments have a similar function but connect two bones. They both have
  complex microstructures consisting of a hierarchical arrangement of colla
 gen fibres embedded in a compliant matrix and can have varied macroscale g
 eometries ranging from cylinders to tapered bands to hourglass shapes. The
  interplay between their micro- and macro-structure makes it challenging t
 o model their mechanical behaviour. In this seminar\, I will present a mic
 roscale constitutive model that can be used to predict how the structural 
 arrangement of the collagen fibres impacts tendon and ligament stress-stra
 in behaviour. I will explain how it can be used to infer microscale parame
 ter values from macroscale mechanical data. Then\, I will discuss its impl
 ementation in a finite element model to investigate the effects of macrosc
 ale geometry\, highlighting the importance of realistic fibre alignment an
 d how this has been neglected in the literature.&nbsp\;
