Greetings,
I am currently modeling sliding wear in Abaqus software. For this purpose, I need to extract the SLIP variable from the model for both surfaces in contact, however Abaqus provides this variable in the output of CDISP only for one surface and gives zero values for the second surface.
According to the Abaqus documentation, the use of General Contact causes two surfaces in contact to be both master and slave at the same time, so the outputs must be written for both, however here it can be seen that the output is written for only one. Is there any way to extract the SLIP variable for both surfaces in general contact formulations?
Thanks in regard
You've not studied the ABAQUS documentation well. Abaqus outputs the contact displacement (CDISP) variable which includes both normal and tangential components (COPEN and CSLIP, respectively). You can access COPEN and CSLIP in the output database. Since SLIP represents the tangential displacement of the slave surface relative to the master, you can calculate the slip on the "master" surface by inverting the sign of the CSLIP value obtained from the output. Referenced section in documentation is https://classes.engineering.wustl.edu/2009/spring/mase5513/abaqus/docs/v6.6/books/usb/default.htm?startat=pt09ch29s02aus115.html

you can use a penalty contact method, node-into-face and edge-into-edge

Thanks for the reply
Right, the relative distances are the same. Abaqus provides CDISP output for every node in contact, however, the ones for one of the surfaces is always zero (seems like it calculated relative to itself). The problem here is that the number of nodes on target surfaces are different thus the number of outputs are different for slave and master so changing sign alone won't solve the problem
Thanks in regard
