Hi

I try to do fatigue crack simulation in general FE code (ANSYS) for 3D formulations. I face very hard to get mesh with crack tip elements (for 2D it s quite easy to use KCON options). Any idea how to perform for the 3D crack tip mesh.

regards

Govind.

Crack tip stress and formation of Plastic/influence zone for composite solid rocket propellants

The necessity to understand the crack behaviour of composite solid rocket propellants as it helps in analysis of service life of rocket motors. Experimental data reveals that a material’s microstructure at the crack tip can have a significant effect on the local damage near the crack tip and crack growth behaviour in particulate composites.
