PNNL State variable model for QP980 and 3Mn steel. (user material 50) 2. PNNL State variable model for 10Mn steel. (user material 47) 3. MSU/OSU combined-constraints crystal plasticity model for FCC and BCC. (user materials 45 and 46, respectively) The usermat packages with the source code, and the corresponding prebuilt executables are available at: http://ftp.lstc.com/anonymous/outgoing/ubasu/icme/ The State Variable model for QP980/3Mn steel is in subroutine umat50v, the one for 10Mn steel is in umat47v, and the FCC and BCC crystal plasticity models are in umat45v and umat46v, respectively, in dyn21.f Please see Appendix A in the Keyword Manual for more details about user-defined materials in LS-DYNA. This branch of the code (branched from R8.0) is available on the SVN server at svn://svn/lstc/ls971/branches/ubasu/icme-umat Thu, 23 Feb 2017 00:00:00 GMT https://hdl.handle.net/11256/932 2017-02-23T00:00:00Z
