SayedHessam posted a new comment: Dear Jan, Thanks for your reply. However, according to my attached script, I want to model my clumps to measure its uniaxial strength of my clumps. I tried to write up a simple model but my model give my strange result I need to model the attached formula and same behavior with same results: https://www.dropbox.com/s/zq7il7cswmo36ee/Unaxial.JPG?dl=0 some reference result: https://www.dropbox.com/s/z5y9kj9ovblfzn1/Typical%20test.JPG?dl=0 My script: from yade import pack from math import * from yade import plot from yade import qt vitesse=0.1 cohN=50e5 cohT=35e5 E=50e9 nu=0.3 d=2310 phi=35 rayon_s=0.005 rayon_g=0.05 rayon_boite=rayon_g+0.0001 espace=0.0 gravity=0 O.materials.append(CohFrictMat(young=E,poisson=nu,density=d,frictionAngle=radians(phi),normalCohesion=cohN,shearCohesion=cohT,label='sol')) O.materials.append(CohFrictMat(young=10e13,poisson=0,density=10000,frictionAngle=radians(10),normalCohesion=0,shearCohesion=0,label='walls')) mn,mx=(-rayon_boite*2,-rayon_boite,-rayon_boite*2),(rayon_boite*2,rayon_boite,rayon_boite*2) walls=utils.aabbWalls([mn,mx],thickness=0,material='walls') wallIds=O.bodies.append(walls) sp=pack.regularHexa(yade._packPredicates.inSphere(center=(0,0,0),radius=rayon_g),gap=espace,radius=rayon_s,material='sol') O.bodies.append(sp) for i in O.interactions: i.phys.unp = i.phys.penetrationDepth def plotAddData(): plot.addData( dspl = O.bodies[3].state.displ()[1], load = O.forces.f(3)[1], ) O.engines=[ ForceResetter(), InsertionSortCollider([Bo1_Sphere_Aabb(aabbEnlargeFactor=1),Bo1_Box_Aabb()]), InteractionLoop( [Ig2_Sphere_Sphere_ScGeom6D(interactionDetectionFactor=1),Ig2_Box_Sphere_ScGeom6D()], [Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(setCohesionNow=True,setCohesionOnNewContacts=False),Ip2_FrictMat_FrictMat_FrictPhys()], [Law2_ScGeom6D_CohFrictPhys_CohesionMoment()] ), GlobalStiffnessTimeStepper(active=1,timeStepUpdateInterval=5,timestepSafetyCoefficient=0.8, defaultDt=utils.PWaveTimeStep()), TranslationEngine( translationAxis=(0,-1,0), ids=[3], label='tl', velocity=vitesse ), NewtonIntegrator(damping=0.3, gravity=[0, gravity, 0]), PyRunner(iterPeriod=10,command='plotAddData()'), ] O.dt=utils.PWaveTimeStep() O.usesTimeStepper=True qt.Controller() qt.View() plot.plots = {'dspl': 'load'} plot.plot() O.saveTmp() Best Regards Sam -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
