"Exploring data and imaging driven approaches to shade light on the biomechanics of soft tissues. Case study: the knee meniscus"
The talk focuses on recent development in exploring the relationship between the internal inhomogeneous porous architecture and the mechanical role that soft human tissues play. Soft tissues are highly porous (>60%) and functionally graded materials, mapping in space the variation of architectural features / mechanical properties is the key to the design of biomimetic synthetic tissues.
The soft tissue analysed here is the knee meniscus which is seen as an optimized-by-nature load bearing and damper system. The time dependent behaviour is ruled by the fluid flow inside the pores which is modelled, in a poroelastic framework, through a fractional pore pressure diffusion equation. Advances in imaging at different scale, mechanical and poromechanics testing, material model selection, machine learning and numerical schemes will be presented.
