To advice from DCBII,
Thanks for your thoughts..
The geometry i am using is completely smooth and tanget - there is a very small radius as opposed to a sharp corner and it IS radiused and has a ton of elemenets across it - It may be that the prototyped samples are not quite the same (although...
To Rons queries,
I don't have a measured value to possions ratio - so i will try some variance of the value here and see if i can get better correlation between the test data.
The specimiens should be fairly free from inclusions etc as the SLA process is fairly consistent however the parts...
Hi,
Sorry its not really a true ceramic though it is supposed to behave in a similar manner - the material is bluestone - data sheet here http://www.3dsystems.com/products/datafiles/datasheets/SLA/DS_Accura_Bluestone_US.pdf
It is more a kind of plastic but it is brittle with no real...
Hello Group,
I am trying to predict fracture of teeth.
The approach has been to 3d scan a tooth and recreate the geometry in ceramic material by rapid prototyping techniques.
The sample teeth are then tested on a load test machine.
Also material samples were tensile tested and i got a...
