I am doing simulation for crack propagation using VCCT. I am doing it for adhesively joined composite plate. 

I want to introduce initial crack for further analysis. How can I introduce initial crack ?

    I am using Nastran as a solver. I found the way of creating initial crack. 

    But, now the problem is reacting force at the crack tip. Do you have any idea how can i find the reacting force at the crack tip. ?

     

    I tried to find the reacting force by applying the RBE as a MPC. But is it right way to find the reacting force at the node of the crack tip ?

    Hi Mayank,

     

    Please contact Nastran Solver support regarding your query,

     

    In OptiStruct GPFOCRCE card will fetch the forces coming on to nodes.
