SubscriberHello
I'm trying to calculate the archard’s wear from a contact between a brake pad on a disc. I succeeded in the case of a block that slides linearly on a flat surface. Now with a pad that crawls along a circular trajectory, with the same settings, I can't get any information. To activate archard’s wear according I acted in the following way:
1) In the contact tab I have inserted a command file:keyopt,cid,5,1 !close gap with an auto contact surface offset
keyopt,cid,10,2 !contact stiffness updateH=10e-13
K=1
m=0,8
n=1,3
TB,wear,cid,,,ARCD
TBDATA,1,H,K,m,nNLADAPTIVE,all,add,contact,wear,0.5
NLADAPTIVE,all,on,all,all,1,,4
NLADAPTIVE,all,list,all,all2) In the results tab I have entered a user defined result with the following settings:
In the exercise with the block sliding linearly it brings me results, while in the exercise with the sliding pad in a circular trajectory it reports the following errors:
They are warnings, the exercise goes to convergence. I also have a note to make, if I don't activate Archard, in the same exercise, those warnings DOES NOT appear.
