应航天航空学院邀请,我校校友、美国国家工程院院士、哈佛大学教授锁志刚教授为我校师生作报告。
报告题目:Soft Active Materials
时 间:6月3日(星期二)下午14:40
地 点:主楼A203
报告摘要
Soft materials can be made active in that they can greatly change shape and volume in response to diverse stimuli. In this talk I'll focus on swelling polymeric gels. Flexible, long polymeric molecules can covalently crosslink into a three-dimensional network. When the network is brought in contact with a solvent, the network imbibes solvent molecules and swells, resulting in an aggregate known as a gel. Gels are used in diverse applications, including medical devices, actuators in microfluidics, and packers in oil wells. Mixtures of macromolecular networks and mobile molecules also constitute many tissues of plants and animals. This talk describes a nonlinear field theory of gels. The theory is illustrated with examples of swelling induced large deformation, contact, and bifurcation.
