      hello sir,


                        i was doing simple fracture analyses of plates. 


      i am getting stress intensity factor  easily but VCCT (G1) and other are not evaluating.


      please see the file and suggest the solution


      thanks

      hello sir 


                     ONE more doubt i have, when we defined the coordinate for crack according to me it should be at crack tip. The same we used for formula also for finding stresses at crack tip.


      i checked the analyses for both coordinate at tip and coordinate away from tip, Stress Intensity factor is different for both cases but deformation is same. please check it.(file attached below)


      this is the link of tutorial explaining the fracture analyses and explaining the coordinate system away from crack tip.
