    Abstract. Results of laboratory tests of a technical coated fabric under the axial and off-axial tension and also biaxial tension with shear carried out by the authors of the article are considered. The purpose of the research was to determine the mechanical properties of materials used when simulating the work of soft shell-type structures. Two different types of a technical coated fabric were used in the experiments: with and without PrecontraintR technology. To measure the displacement and strain fields on the surface of specimens, the method of digital image correlation has been used. Numerical simulation of technical coated fabrics, imitating carried-out laboratory tests, has been executed with the use of software program "Ansys Workbench". When analyzing the results of numerical experiments it is revealed that shearing stresses make a significant contribution to the stress-strain state of the material. The possibility of applying several classical criteria for fracture strength of composite materials in order to predict and evaluate the behavior of technical coated fabrics under load is shown.
    Key words: technical coated fabric, soft shell-type structures, laboratory tests, numerical simulation, digital image correlation.
