Abstract

The paper presents experimental results obtained for Necuron 1020 rigid polyurethane specimens with stress concentrators, at traction test. Resistances of these specimens are evaluated based on the critical distances theory, obtaining a good agreement with experimental results.

Keywords: rigid polyurethane, critical distances theory
