ANALYSIS OF NON-LINEAR ELASTIC MATERIAL PROPERTIES OF PVC-COATED PANAMA FABRIC

Abstract

The aim of the present paper is to propose a method of laboratory tests to determine non-linear elastic properties of coated Panama fabric. The material parameters are specified on the basis of uniaxial tensile tests in the warp and weft directions. Techniques based on the least squares’ methods are used in the determination process. Reduction concepts of the strength parameters are proposed in order to take into account rheological effects in the fabric. Numerical applications to MSC.Marc, a commercial program, are presented. A user-defined HOOKLW subroutine is used to introduce the non-linear elastic properties of the PVC-coated fabric into the MSC.Marc system.

Keywords:

non-linear elastic modeling, PVC-coated fabric, MSC.Marc
