J0110103 A dynamic behavior analysis of jet-engine fan blade under impact loading

Abstract

A dynamic behavior analysis on CFRP-made jet-engine fan blade has been performed by using K-computer. The simulation aimed to model a bird strike event by using an SPH-FEM weak-coupling analysis, where a single finite element is assigned to each unidirectional CFRP prepreg layer in the thickness direction of the fan blade. As a fundamental study, we performed an impact analysis with about 3.5 million elements using 8192 cores. The massively parallel simulation realized a dynamic behavior analysis of the full-scale fan blade model under impact loading.
