The complex molecular nature of rubberlike materials, polymers, proteins (such as collagen and elastin) and biomolecules such as DNA require the use of nonlinear theories to describe their mechanical behaviour through the development of realistic mathematical models. The theory of incompressible, isotropic hyperelasticity is a starting point for the modelling of such materials at both the microscopic and macroscopic scales. The aim of the Workshop is to explore the possibility of building upon recent work by bringing together experts in mathematical modelling at the molecular, mesoscopic and continuum levels and experts in the emerging field of biomolecular mechanics. This will hopefully generate new interdisciplinary collaborations that will advance understanding of the role of mechanics in biology at the molecular level.The Workshop will include experimental, theoretical and computational modelling of the mechanics of polymeric materials, biomolecules and proteins and their influence on the response of biomaterials at the macroscopic (continuum) level within the framework of nonlinear elasticity and related theories, with particular reference to transitions between scales.
