Mechanics of Large Deformation in Soft Solids

Deadline: Open all year round

Project Description

Solid materials that can undergo large deformations are ubiquitous in nature and are widely used to manufacture engineering components.

Naturally occurring materials include soft biological tissues such as heart, arteries, skin and brain. Study of their deformation characteristics is not only important to understand biological function but also necessary to develop an efficient treatment for medical conditions (design of coronary stents, skin patches and surgical procedures).

Several advanced composites used in aircraft and spacecraft components, artificial muscles in advanced robotics and substrates for flexible electronic devices also fall under this category. Of great interest are smart magneto-active and electro-active materials that can undergo extremely large, rapid, and reversible deformations just at the flick of a switch and therefore present great promise for future applications.

This project aims at mathematical and computational modelling of large deformations in soft solids described above. Models for material response will be developed with the help of experimental observations. Computer simulations will be performed to predict the response of these new models under physically relevant loading scenarios. Extreme deformations often lead to buckling instability. Instability is associated with material/structural failure in traditional engineering design but in the case advanced soft composites instability is a desirable and useful tool. One of the main aims of this project is the prediction of post-buckling response of soft materials.
