I have experiment by using strain gages series which mounted along crack path propagation direction, I can find exactly the initatial time of crack but not know how to find arrest time of crack. Crack tip stops between 2 strain gages and the signal of them can be got. Following is the Figure of strain gage mounted on specimen.

Dear,

 Please show me what are and how to determine the Kinetic energy, Strain energy, Fracture energy during propagating of crack.

Thanks,

Dear Alls;

Would you please explain for me why Dynamic J-integral increases when crack propagates, and why Dynamic J-integral are independent with difference paths.

Best Regards;

Chau 

Dynamic J-integral, help!!!!!!!!!
