Project Title:
The Geometry and Physics of Wrinkling
Supervisor:ALTMAN Michael Scott
Project Description:Wrinkling of two-dimensional membranes commonly occurs throughout nature. This takes the form of a ripple morphology with quasi-periodic sinusoidal shape when a membrane experiences longitudinal tensile and/or shear stress. The amplitude and wavelength of ripples is determined by the minimization of the energy costs associated with transverse bending and longitudinal stretching along ripples that are related to the elastic properties of the membrane. In this project, we will review and understand the literature on the geometry and physics of wrinkling, and plan experimental table top measurements to test the underlying theoretical concepts.
Course type: UROP1100  
Applicant's Roles:The student will read publications on the theory and experimental measurements of wrinkling of membranes. Through independent study and weekly meetings with the supervisor, the student will develop an understanding of the theoretical basis of wrinkling. The student will also develop a plan for table top apparatus to study wrinkling in common membranes such as polymer films.  
Applicant's Learning Objectives:1. develop an understanding of the elastic properties of materials 2. gain experience in practical experimental physics concepts 
Complexity of the project:Challenging
