Abstract: The mechanisms of wrinkling in compressed polymer films of varying thickness are studied alongside existing models. I explore how a theory that describes discrete wavelengths at a constant thickness can accommodate a regime with a continuous change in thickness. I produce films with different thickness profiles and compare them to fluid dynamics theory. I then apply the existing model for the formation of wrinkles to find the expected wavelength profile and assess its applicability. The formation and development of wrinkles is described, and defects are rationalized and explored in planar and cylindrical regimes.
