Summary on Grant Application Form |
|
The project aims to develop a numerical tool to describe the static mechanical response of hollow composite sections subject to arbitrary loads. These types of structure are found in primary structural parts such as: helicopter rotor blades; tailplane; offshore platforms; sporting equipment such as tennis rackets, ski poles and golf clubs. The model will extend the work undertaken by other researchers to include material bi-modularityl through-thickness stresses, large rotations in addition to material anisotropy and warping responses. The one dimensional model will be developed by postulating a suitable displacement field. Appropriate sectional properties will be calculated for arbitrary closed form sections by finite element analysis (FEA). The model will be embodied in software that links with current FEA software such as Abaqus and Nastran. The model will be validated against known closed form solutions and by conducting a case study on a helicopter rotor blade. GKN Westland Helicopters will provide necessary data for this. Effects of material anisotropy and stacking sequence on structural response will be quantified.
