[Yade-dev] TriaxialTest regression tests.

2010-12-03 Thread Anton Gladky
Hi, As I understand TriaxialTest one of the most popular test in Yade. Can anybody add a regression test for that? Thanks Anton ___ Mailing list: https://launchpad.net/~yade-dev Post to : yade-dev@lists.launchpad.net Unsubscribe :

Hi Chiara, (revno 2587) - I restored Plassiard definition of Kr. Your definition is still optionaly available (flag useMeanRad). Using R1*R2 makes sense IMO, since stiffness combine via harmonic averages. - The flag momentRotation is disabling moments by defaults, so default 0 for alpha's was

Bruno, I understand now the formulation of Plassiard. In the paper he is used to define the contact stiffnesses in a different way than we do. He is using the mean radius to get them whereas we employ the radius of each particle in the calculation. Hence, in our case, it makes sense to use Da*Db

have them). Also, if you do not use the radius mean, there would be the problem on how to define the maximum plastic value (again, Plassiard was using the radius mean x Fn). We need to make it consistent either we use the radius mean or not. I let you shortly know. I would use min(r1,r2)*Fn,
