## Abstract A numerical analysis for the assessment of wrinkle formation tendencies in sheet metals is presented. A doublyβcurved thin shell element under biaxial plane stress states is considered, and the critical stress values for wrinkling are determined. The analysis is based on plastic bifurca
High precision stress-strain curves were determined from representative Type A Mylar sheets in several commercially available thicknesses. A representative value for Young's modulus was found to be 0.76 X lo6 psi. Measured values were from 0.60 to nearly 0.78 X 106 psi with the maximum value occurri
Non-linearly distributed, in-plane, tension at the edges of a thin, flat, rectangular material with small flexural stiffness, called a web, can cause it to wrinkle. Airy stress functions are determined in closed form for webs under arbitrarily prescribed, in-plane, edge loading. The loading at impen
