I ve modelled concrete as C3D8 and rebar as T3D2 elements as Concrete Damage plasticity model and Damage for Traction Separation Laws as Maxps Damage . Also defined XFEM crack .Also checked in output variable as PHILSM, PSILSM and STATUSXFEM.
But also i m not getting a crack .
Hey Roshan...i think; first of all; you need to have a true model. in the below link you can find what do you need. also it may cost for you but so many CDP model I've found there: https://numericalarchive.com/shop?olsPage=t%2Fconcrete-structures
The crack and cracking propagation could be observed by LE, PE or DAMAGET, which are all connected with each other. For instance, the areas whose LE are greater than ft/Ec could be assumed to have cracked, theoretically. In addition, you can also select DAMAGET, if you have defined the Tensile Damage Coefficient in the CDP model, to observe crack propagation.
Here is our works, and hope we have further discussion about CDPM
