hello
i am using modified JC model for the simulation of segmented chip formation in machining of Ti64 alloy and i wrote a VUHARD subroutine for that,but two problem arises,
1.the simulation stops at higher value of frictional co-efficient and
2.the feed force is under predicted
since i didn't use dyieldDeqps,is it necessary?
plz help!
thanx a ton in advance!!
