ABSTRACT
Uniaxial and biaxial tensile tests are chosen from a large group of experimental tests (see e.g. Ambroziak & Kłosowski 2013) to model the material behaviour of a PVC foil. The aim of the laboratory tests is to determine mechanical properties of a polymer, named DPS stretch ceiling. According to the technical data specified by the manufacturer (https://www.grupadps.com/en/) the following properties are defined: weight 240 g/m2, total thickness 0.17 mm, tensile strength for longitudinal and transverse directions 17.1 N/mm2 and 18.7 N/mm2, respectively. The tensile strength is established according to PN-EN ISO 527-1. Material parameters necessary to analyze a real structure were not found in technical specification. In order to perform a relevant assessment of a material, laboratory tests were carried out.
