stress concentration at the crack initiation location while operates at 120Hz frequency.how to do using abaqus software tool.Is there any one previously worked in this area.kindly assist me to resolve this problem.

I was looking at the stress concentration at a corner for both a mode I and mode II loading situation.

For reference, see: Carpenter, 1984. Mode I and mode II stress intensities for plates with cracks of finite opening. International Journal of Fracture. V. 26. 201-214. 1984.

The problem that is being addresses is the stress concentration found at a corner in an infine body as seen in the figure below. β=0...π.
