Hi,
There is no need for LS Dyna for fracture analysis, Static Structural is sufficient for fracture analysis. 

Please refer the following links for more information:
5.5. Fracture Analysis (ansys.com) 
ANSYS Mechanical: Fatigue Crack Growth Analysis using SMART Crack Growth (youtube.com)

Also, it would be helpful if you could specify whether you want to know the fracture toughness of the material or just do the fracture analysis...
