New question #660540 on Yade: https://answers.launchpad.net/yade/+question/660540
Hi guys! I am trying to calibrate the model with the triaxial test. I used CohFricMat as a material and Cohesionmoment for the Contact law. The soil is sand with cohesion. So I have to work with 5 parameters to match the result of the experimental test with the triaxial test. These parameters are E, Ks/Kn, Phi, eTaRoll and alphaKr. Hence, I have a general question about YADE which Are there any limitation for parameters? it means is there any minimum and maximum value for contact (i.e. CohFrictMat) parameters? For instance, I used these value for my model: from yade import pack,plot ############################################ ### DEFINING VARIABLES AND MATERIALS ### ############################################ # The following 5 lines will be used later for batch execution nRead=readParamsFromTable( num_spheres=5000,# number of spheres compFricDegree =30, # contact friction during the confining phase key='_triax_base_', # put you simulation's name here unknownOk=True ) from yade.params import table num_spheres=table.num_spheres# number of spheres key=table.key targetPorosity = 0.49 #the porosity we want for the packing compFricDegree = 30.6# contact friction during the deviatoric loading finalFricDegree = 10 rate=-0.1 # loading rate (strain rate) damp=0.70 # damping coefficient stabilityThreshold=0.01 # we test unbalancedForce against this value in different loops (see below) young=1e6# contact stiffness mn,mx=Vector3(0,0,0),Vector3(0.09,0.18,0.09) # corners of the initial packing ## create materials for spheres and plates O.materials.append(CohFrictMat(alphaKr=40,young=young,poisson=0.2,frictionAngle=radians(30),normalCohesion=0,shearCohesion=0,momentRotationLaw=False,etaRoll=0.05,density=2600,isCohesive=False,label='spheres')) O.materials.append(CohFrictMat(young=young,poisson=0.2,frictionAngle=radians(30),density=0,label='walls')) Cheers Hessam -- 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 : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
