Any Idea, how one can perform fatigue analysis of structural ceramic materials?
Thanks.
Hi Giri,
what material propertied do you have for ceramic?
What is your end objective?

ALON, aluminium nitride.
Major props:
Structure Cubic, Spinel Lattice Constant 7.956–7.936 Å Density 3.69 g/cc Form Polycrystalline Melting Point 2150°C Young’s Modulus 320 GPa Shear Modulus 135 GPa Poisson’s Ratio 0.24 Hardness 1800±100 kg/mm2 (Knoop indentation, 200g load) Fracture Toughness 2.0MPa-m1/2 Flexure Strength 300-700 MPa
Specs: http://www.surmet.com/pdfs/ALON%20Data%20Sheet.pdf
Objective: Cyclic loading. HCF. Find the damage, life expectancy.

And Weibull model is used for reliability analysis, instead of SN curve. No idea, how can I use it in Hypermesh.
Hi,
If model is having shell elements you can try with Radioss XFEM to simulate crack propagation.

Great but I don't have any idea. Is their any documentation (tutorial) or sort? Can't it be done in Optistruct?
I have attached few examples of XFEM for crack propagation.From Radioss 14.0 it will work for solid elements aswell.
In Optistruct we can do fatigue analysis using stress & strain based approach(Not sure for cermaics).Refer online tutorials for more information.
