Background:

An opportunity has arisen within the Department of Me
chanical and Aerospace
Engineering at the University of Strathclyde for a suitably qualified graduate to
undertake a three year
PhD

research project investigating the
development of
advanced analysis tools for the composites aerospace industry principally
in
investigating methods for reducing and optimising Spirit Aerosystems
design/analysis aerospace product cycle time.


The project is

jointly

funded by the
University of Strathclyde

and

an industrial
collaborator,
Spirit Aerosystems Ltd, a leading composi
tes wing
structures

manufacturer based in Prestwick, Scotland
. The project offers

a tax free stipend
of approximately £1
3
000 per year throughout the duration of the project.


Composite structures tend to be analysed using traditional modelling and
simulati
on methods based on conventional metallic materials, the result is often
described as a “black metal design”, resulting in over engineered and heavy
components with very long, expensive and not sustainable design and
manufacturing cycle.


Currently a sign
ificant amount of the design/analysis cycle is spent creating finite
element models from CAD geometry, determining critical load cases, extracting
element loads, and subsequently carrying out structural optimisation and closed
form calculations using tradi
tional analytical calculations (e.g. bolted joint checks
and through thickness strength checks for laminated composite structures).
Developing tools which can efficiently optimise and automate these processes
has the potential to significantly reduce o
verall analysis time, allowing more time
for product optimisation, and reduce overall product development costs.


Composite optimisation analysis tools seem to have limited applicability and do
not account for new composite materials specific manufacturing

constraints,
developing optimisation techniques capable of coping with composites
manufacturing constraints and able to communicate with state of the art CAD
software industrial packages would represent a significant advancement against
current state of
the art modelling and simulation practices.


The PhD study programme will investigate (but is not limited to):




Tools /methods which enable rapid generation of finite element models
from CAD data



Tools/methods which enable rapid evaluation and optimisation

of complex
CFRP structures, accounting for major design drivers such as:



Fastener bearing/bypass interaction analysis



Through thickness strength analysis (curved beam)



Local failure mode analysis of sandwich structures



Manufacturing constraints implement
ation within structural
optimizer



Composite Fabrication process down selection as main component
optimisation output



Tools/methods which enable rapid generation of results and reporting



Seamless interface between FEM optimised model and CAD software
tools



Specific case studies for aerostructures components design and
optimisation
