Continuum mechanics approaches have been used to model the mechanical behaviour of biological (and active) systems at length scales that are large enough.
For example, when analysed at the micron-scale, biological membranes can be treated as continuum objects that deform regulated by effective properties such as curvature mismatch or active forces. Those effective properties depend on how their fundamental constituents, such as lipids and proteins, evolve at the nano-scale.
Continuum modelling approaches have been able to improve the understanding of the behaviour of biological materials, showing the critical role of mechanics in processes like growth and remodelling, but they have two major limitations:
The project focuses on providing a link between the microscopic (discrete) nature and the macroscopic (continuum) modelling of biological structures with the double-pronged aim to improve the understanding of the two limitations described above: (i) to provide a quantitative relation between the lumped parameters used in the continuum description and the microscopic mechanics from which they originate them; (ii) to reveal what scale is large enough for the continuum approaches cannot be used.
The project aims to develop new theories to understand the root causes of the active morphing of two-dimensional biological membrane-like structures.
The project involves three aspects:
During this project, you will be part of the Institute for Infrastructure and Environment. You will join a vibrant community of PhD students, postdoctoral research associates and academics.
