New question #700258 on Yade: https://answers.launchpad.net/yade/+question/700258
Hi, I am simulating a triaxial compression test using Hertz-Mindlin model, and I'd like to ask that if it is possible to include adhesion in Hertz-Mindline contact model so that I can simulate bonded material (or cement material). I read from MindlinPhys[1], there seems to be an option to set adhesion (named adhesionForce in [1]). #I use FrictMat: MatSand = O.materials.append(FrictMat(young=young,poisson=0.3,frictionAngle=radians(30),density=2650,label='sand')) #The engines I used are as follow: O.engines=[ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Box_Aabb()]), InteractionLoop( [Ig2_Sphere_Sphere_ScGeom6D(),Ig2_Box_Sphere_ScGeom()], [Ip2_FrictMat_FrictMat_MindlinPhys(betan=betan,betas=betas,label='ContactModel')], [Law2_ScGeom_MindlinPhys_Mindlin(includeMoment=False,includeAdhesion=True,label='Mindlin')] ), GlobalStiffnessTimeStepper(active=1,timeStepUpdateInterval=100,timestepSafetyCoefficient=0.8), triax, TriaxialStateRecorder(iterPeriod=100,file='WallStresses'), newton, #PyRunner(iterPeriod=2000,command='history()',label='recorder'), #PyRunner(command='stopIfDamaged()',iterPeriod=500), ] #I tried to use the following command to active adhesion: ContactModel.isAdhesive=True ContactModel.adhesionForce=adhesion But I didn't make the adhesion come into effect. Thereby, I'd like to ask that: (1) How to include adhesion in Hertz-Mindline contact model if it is possible. (2) In [1], it explains adhesionForce as "Force of adhesion as predicted by DMT", what is DMT? (3) Where I can find the source code of Hertz-Mindline contact model in Yade trunk? Thanks!
