The Chair will investigate nonlinear dynamics and stability, fluid-structure interactions and active control of shell structures for biomedical and aerospace applications. There are similarities between the shells of aircraft, space rockets and those for biomedical applications. These structures are usually made by a skin that is conveniently modelled as a shell. However, the material properties are very different. Shells made of advance composite and soft materials will be studied, introducing hyperelasticity and viscoelasticity as well as large deformations. The human aorta will be modelled with pulsatile blood flow inside a soft laminated hyperelastic and viscoelastic shell.

椅子将研究非线性动力学和稳定性，流体结构的相互作用以及对生物医学和航空航天应用的壳结构的主动控制。飞机，太空火箭的炮弹与用于生物医学应用的壳之间有相似之处。这些结构通常是由方便地建模为外壳的皮肤制成的。但是，材料特性非常不同。将研究由预先复合材料和软材料制成的贝壳，引入超弹性和粘弹性以及大变形。人主动脉将在软层压的超弹性和粘弹性壳内部以脉动血流进行建模。
