    • Analysis of in vivo skin anisotropy using elastic wave measurements and Bayesian modelling 

      Nagle, Matt; Price, Susan; Trotta, Antonia; Destrade, Michel; Fop, Michael; Ní Annaidh, Aisling (Springer, 2023-04-06)
      In vivo skin exhibits viscoelastic, hyper-elastic and non-linear characteristics. It is under a constant state of non-equibiaxial tension in its natural configuration and is reinforced with oriented collagen fibers, which ...

    • Automated estimation of collagen fibre dispersion in the dermis and its contribution to the anisotropic behaviour of skin 

      Ní Annaidh, Aisling; Destrade, Michel; Gilchrist, Michael D. (Springer, 2012-08)
      Collagen fibres play an important role in the mechanical behaviour of many soft tissues. Modelling of such tissues now often incorporates a collagen fibre distribution. However, the availability of accurate structural data ...

    • Bending instabilities of soft biological tissues 

      Destrade, Michel; Ní Annaidh, Aisling (Elsevier, 2009-12-15)
      Rubber components and soft biological tissues are often subjected to large bending deformations while 'in service'. The circumferential line elements on the inner face of a bent block can contract up to a certain critical ...

    • Characterising the anisotropic mechanical properties of excised human skin 

      Ní Annaidh, Aisling; Destrade, Michel; Gilchrist, Michael D. (2012)
      The mechanical properties of skin are important for a number of applications including surgery, dermatology, impact biomechanics and forensic science. In this study, we have investigated the influence of location and ...

    • A combined experimental and numerical study of stab-penetration forces 

      Ní Annaidh, Aisling; Cassidy, Mary; Curtis, Michael; Destrade, Michel; Gilchrist, Michael D. (Elsevier, 2013-12)
      The magnitude of force used in a stabbing incident can be difficult to quantify, although the estimate given by forensic pathologists is often seen as 'critical' evidence in medico-legal situations. The main objective of ...

    • Deficiencies in numerical models of anisotropic nonlinearly elastic materials 

      Ní Annaidh, Aisling; Destrade, Michel; Gilchrist, M.; Murphy, J.G. (Springer, 2013-08)
      Incompressible nonlinearly hyperelastic materials are rarely simulated in finite element numerical experiments as being perfectly incompressible because of the numerical difficulties associated with globally satisfying ...

    • Non-invasive evaluation of skin tension lines with elastic waves 

      Deroy, Claire; Destrade, Michel; Mc Alinden, Aidan; Ní Annaidh, Aisling (Wiley, 2017-11-20)
      Background: Since their discovery by Karl Langer in the 19th Century, Skin Tension Lines (STLs) have been used by surgeons to decide the location and orientation of an incision. Although these lines are patient-specific, ...

    • Tension lines of the skin 

      Ní Annaidh, Aisling; Destrade, Michel (Springer, Cham, 2019-05-29)
      Skin tension lines are natural lines of tension that occur within the skin as a result of growth and remodeling mechanisms. Researchers have been aware of their existence and their surgical implications for over 150 years. ...
