Abstract
Fan blade shedding or fan blade-out (FBO) involves the failure and release of fan blades from the fan disc due to foreign object damage (FOD). This typically leads to severe damage to the engine and its surroundings. Due to the potential severity of FBO events, all engine manufacturers include a containment ring, which surrounds disc to absorb the kinetic energy of the released blade and contain blade fragments within the confines of the disc so that they do not pierce fuel tanks, hydraulic control lines or the fuselage. Unfortunately, current containment ring designs are somewhat inadequate and better designs are needed not only to contain the blade and its fragment but also to arrest it away from the incoming trailing blades.
Accordingly, this study is concerned with the design and analysis of a novel containment ring design for turbofan engines using dynamic nonlinear finite element (FE) simulations and a functional scaled down instrumented blade-out test rig. Four aspects of the work were accordingly examined. The first is concerned with the response of different containment ring materials to the released blade. This enabled the selection of the most appropriate material combination for the containment ring. The second with the response of the selected containment ring to blade-out impacts with partially and fully bladed fan disc. The third with the calibration of the finite element predictions using a functional scaled down test rig and to examine the true trajectory of blade-out in gas turbine engines. The fourth with the use of two containment rings design not only to contain the released blade within the confines of the disc, but also arrest it away from the path of the incoming trailing blades without introducing large weight penalties or affecting the aerodynamics of the engine.

Abstract
Integrated earthquake simulation of a whole city is a challenging subject to realize a more reliable estimation of earthquake hazard and disaster. This simulation sequen-tially combines numerical analysis methods for all the processes of an earthquake, such as earthquake wave generation and propagation, structural seismic responses, mass evacuation, and economic recovery processes. The earthquake simulation is able to make higher resolution estimation by taking advantage of rapidly growing modern computers together with digital information of urban area which are being accumulated.
This lecture first explains the two basic techniques that are needed for the integrated earthquake simulation: 1) the utilization of high performance computing for large scale numerical analysis; and 2) the automated model construction for urban areas by assembling various digital data. High performance computing is essential for a regional scale simulation with higher spatial and temporal resolutions. An analysis model of high fidelity needs to be constructed for each numerical analysis method.
To demonstrate the usefulness of the integrated earthquake simulation, the lecture shows two examples of actual cities in Japan, Tokyo City for Tokyo Metropolis Earthquake and Osaka Area for Nankai Trough Earthquake. The results of the nu-merical simulations such as ground motion distribution, structural seismic respons-es, traffic network damages and economic recovery processes, are presented, which are obtained by analyzing automatically constructed models for these two cities and using K computer, a supercomputer in Japan.
Keywords: Integrated earthquake simulation, High performance computing, Automated model construction.
