algorithm of the rotBondedInteraction model

Asked by aaron

Hello ESyS users,

I am learning the rotBondedInteraction model. I cannot really understand the algorithms hidden behind the codes. Is there anybody who can help? I just want to get some materials about the model, e.g. paper, book. I also noticed that in the source code of RotBondedInteraction.cpp, some equations have been implemented in the function CRotBondedInteraction::calcForces(). Could anyone tell me where can I find these equations? Is there any paper I can search for?

Thanks a lot.

Best,
Aaron

Hi Aaron,

The full details on the rotBonded interaction algorithm can be found in:

Wang, Y.C. (2008) "A new algorithm to model the dynamics of 3-D bonded rigid bodies with rotations", Acta Geotechnica, DOI 10.1007/s11440-008-0072-1

The equation numbers in the source code refer to this paper. If you are unable to obtain a copy, email me directly.

Cheers,

Dion
