Is there any table which determines the characteristics of different type of ceramics such as NiO and SDC , that could be helpful as an input of modeling ?
i think so. for modelling you may use mathematica software or similar. about tables i think ive got a book on my studio. tomorrow, ill try to search. ok?
its 3:30 am. and im tired..... ok?
Dear Paulo,
Thank you so much for your kind support. Actually I have done an experiment to form a circular ceramic pellet under compaction pressure (Under different pressing loads).
I'm interested to simulate its deformation using Abaqus, however I will follow your suggestion as well.
I will be so pleased if you have any books in this field.
Regards.
Hi again
I think that you are abble to simulate it with abaqus. I don't know how rto work with it, but you on web can find it and severall information related.
I've been on FNAC and on several bookshops and I was not abble to find anything about it....
However, I've made a search using the portuguese translation on google.com
"Pelotas em ceramica" and
"Ceramicas- pavimentos"
I was able to find info on brasil and in portugal and I think that if you do the same, on google and use translator online for each page, you will, certainly find something for your research.
If nothing of this is usefull , let me know and I'll try again with other keywords or use other means...
ok>?
Your question should be formulated more properly. What type of deformation you are writing about? Elastic? Plastic? At higher or room temperatures? In the case of such great uncertainty practically there is no correct answer for your question...
Dear Igor,
Thank you so much for being so precise. Actually the deformation is both plastic and elastic since the ceramic powder are under compaction pressure at the room temperature.
During the sintering time the pellets will be under thermal stress , so the deformation is plastic.
( Please pay attention that there is no chemical connection between the mixture of the ceramic powders. )
Regards.
The pressing and sintering processes in powder technologies are very specific. We don't use the term "deformation" in this case, e.g. in the theory of sintering it is usually called "shrinkage". You need to read special literature on the theory of pressing and sintering proceedings in powder metallurgy and ceramics technology. There is a lot of textbooks on this topic.
