Mechanics of Biomaterials

One of the main research focuses of Mechanics of Advanced Materials is on deformation, damage and fracture of biological and biomedical materials.

Our Aim

Understanding mechanical properties and performance of biological materials and their responses to different loading and environmental conditions is becoming increasingly important for development of new medical procedures and devices. Such materials, in contrast to traditional structural materials, demonstrate complex hierarchical microstructures formed by constituents with non-trivial mechanical behaviours (e.g. non-linear high deformations). Additionally, they are characterised by a high extent of variability in their microstructure and properties affected by many factors, including age, health state, nutrition, exercise etc. All these features presuppose development of new experimental, analytical and numerical approaches to assess and predict deformation, damage and fracture behaviour of biological materials and their main constituents.

Our Research

The project is based on a combination of experimental and numerical techniques focused on characterisation of interaction between microstructure (morphology) and mechanical properties of biological materials at various length and time scales. Nano- and micro-indentation, X-ray micro computed tomography, DMA (dynamic mechanical analysis) and microscopy as well as different loading schemes (including creep, relaxation and/or dynamic loading) are used to analyse such materials. Numerical studies use multi-scale schemes employing finite elements, smooth particle hydrodynamics etc. and include development of special elements, subroutines or codes.

Our Outcomes

The obtained mechanical parameters of biomaterials and developed characterisation and numerical tools will support a transition to personalised medical procedures as well as contribute to design and optimisation of medical implants and devices.

“Mechanics of biomaterials is a new frontier in mechanics of materials. Predictive capabilities, based on understanding of deformation, damage and fracture mechanisms in biological and biomedical materials – and at their interfaces – are required by modern healthcare engineering.”
