Hi Luc, Thank you so much for your reply. I am appreciate that you wrote the constitutive model is so clear. It is easy to understand. Thank you again. Cheers Liqing

I think you are right, it should be written ratio=MomentMax/scalarMoment; instead of ratio *= MomentMax/scalarMoment; // to fix the moment to its yielding value It is always good to have someone behind your shoulders to avoid this kind of error ;-) Feel free to commit the change. Otherwise I will try to do it ASAP. Luc 2010/11/17 jiaoliqing<[email protected]> Hi Luc Scholtes, I have read the code in CohesiveFrictionalPM.cpp written by you. I read them carefully, so I found there would be a bug in the file. In the part of description of moment, this part of code is as followed: /*Plastic moment */ if(scalarMoment > MomentMax) { Real ratio = 0; ratio *= MomentMax/scalarMoment; // to fix the moment to its yielding value moment *= ratio; moment_twist *= ratio; moment_bending *= ratio; } Furthermore, the same code is in CohesionlessMomentRotation.cpp to calculate the moment when the moment is over the plastic limit. It is distinct bug that is " ratio *= MomentMax/scalarMoment;". it is written as this, then the ratio will still be zero during the simulation. Then the moment will be zero in the plastic stage. That is different from the algorithms. So, this one should be changed to "ratio = MomentMax/scalarMoment;", others don't need to modify. Do you agree with me? Look forward your reply. thank you!
