Mechanical behavior of PVC-U window elements under static loads

Abstract

In the present work the results, obtained from a study on the mechanical behavior of the casement and sash window elements, made by unplasticized polyvinyl chloride (PVC-U), are presented. The study was conducted with three and five chamber profiles according to the EN 514:2018 standard. The results show that the fracture take a place by the cracks of mixed type - initiate at the welding and propagate in the material. A conclusion for the breaking force and deformation is presented for various values of the heating temperature and melting time. The results can be used for model selec- tion and its parameters identification during numerical modeling of the fracture of the corner joints of the window frames.
