Web Material Effects on Wrinkling Instability Experimental and Computer Analysis

Nilkanth,Vinay K.
Abstract
Permanent creases or wrinkles in a web are costly, due to large amount of wastage associated with the wrinkles. This makes it necessary to investigate wrinkle formation from all aspects. This project especially involves investigation into the roll that the web material and its thickness have In the generation of a wrinkling instability. It involves the material behavior of the web, including possible elastic anisotropy, and web thickness on the development of the shear and longitudinal wrinkles. A simple computer model was developed on NASTRAN to aid the experimental outcomes.
