Vuhard

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!!

vfric subtourine

i am working on the fully coupled analysis of segmented chip formation in machining but the general friction model does not give the right result.so i want to use vfric subroutine,can any body help me writing the code.

plz help
