APPLICATION OF THE MURNAGHAN MODEL IN ANALYSIS OF NON-LINEAR ELASTIC MATERIAL PROPERTIES OF PVC-COATED FABRIC

Abstract

The aim of the present paper is to propose a method of laboratory tests necessary for identification of non-linear elastic properties of the PVC-coated Panama fabric often used for hanging roofs. Two methods of describing the fabric’s non-linear behaviour are investigated: piece-wise linear relations between stress and strain are assumed and the Murnaghan model of solid behaviour is applied. The material parameters are specified on the basis of uniaxial constant strain rate tensile tests in the warp and weft directions. Techniques based on the least squares methods are applied in the identification process.

Keywords:

non-linear elastic modelling, Murnaghan model, PVC-coated fabric
