Structural integrity assessment of rigid polyurethane components using energy methods
Abstract
In the paper, the experimental results of the mechanical investigation have been presented. The main attention was paid to fracture toughness, tearing resistance and fatigue crack growth rate characterization of polyurethane elastomers in terms of two different hardness configurations; 80ShA and 90ShA. The impact of material hardness on the fracture properties (static and cyclic) is reflected in experimental results. For fracture toughness characterization, the EWF (essential work of fracture) method was involved. It has been shown, that the 80ShA and 90ShA materials demonstrate completely different behavior under high stress concentration condition. From the perspective of usefulness of fracture mechanics, the energy approach seems to be crucial in the context of the real operating conditions of the bushing in suspension system of vehicles. For this purpose the fatigue crack growth rate test was performed on planar specimens PS (Pure Shear). Based on the experimental results, it can be concluded that fatigue crack growth rate in 90ShA PUR elastomer was significantly higher in comparison to the 80ShA PUR elastomer. (C) 2018 The Authors.
