This thesis concerns the crashworthiness of helicopters onto water and presents a comparison between test and simulation for the impact of a typical helicopter sub floor section onto both hard and water surfaces. ...

The core goal of this research is to develop an ice impact modelling methodology for ice impact on aircraft structures. The main current limitation of ice impact analysis is the ice constitutive model, so this research is ...

Many metals used in modern engineering exhibit anisotropy. A common assumption when modelling anisotropic metals is that the level of anisotropy is fixed throughout the calculation. As it is well understood that processes ...

The SAFE Structural Analysis procedure is an idealisation error control methodology devised for linear static finite element analysis. This study examines the applicability of this process to non-linear problems. The studied ...

The improvement of the numerical capabilities of predicting the structural loading of high speed, low angle impacts, such as an aircraft during ditching, is addressed in this thesis. Research into the phenomenon of ditching, ...

The aim of this thesis is to provide an investigation toward a rigorous derivation of a stable and consistent numerical method based on the established Smoothed Particle Hydrodynamics method. The method should be suitable ...
