Crack Growth Simulation in the Compressor Blade Subjected to Vibration Using Boundary Element Method

Abstract:

This paper presents results of numerical crack propagation analysis of the compressor blades subjected to transverse vibrations. For stress intensity factor calculation in the half-elliptical crack, a dual boundary element method was used. In this analysis the automated remeshing procedure was used for creation of numerical models with a different crack size. Obtained results of numerical calculations were compared to results of experimental investigations performed for PZL-10W engine compressor blades tested in resonance conditions.
