| dc.description.abstract | The present work deals with representation, design, analysis and fabrication of
Functionally Graded Materials (FGMs).
First, a general overview on FGMs is described. A new and precious definition has been
made. Structures, characteristics and application have been described.
Second, a systematic review of previous research on representation, modelling, design,
design optimisation, property analysis is summarised. Important methods, algorithms,
tools and procedures are investigated and evaluated.
Third, based on the review, a new method for represent, design and fabricate FGMs,
called function-depending layer generation method, is proposed. A complete process
chain with algorithms, procedures, tools and methods is developed.
Fourth, development of Metal Printing Process – Phase 1 at Data-integrated
Manufacturing laboratory is completed. The Fabrication of FGM layers with desired
gradation in material composition and microstructure is realised. It has been combined
with the function-depending method to provide a further extended process chain,
starting from 3D modelling in CAD system and ending with deposited FGM layers with
metal powders according to the desired function..
Fifth, versatility of the function-depending method has been developed that Additive
Manufacturing processes with CNC-based material deposition method can be used on
the generated layer information for fabrication of FGMs. | nb_NO |
