Abstract: The substructure coupling of
FEM for solving the transient temperature and thermal stress
fields in large axisymmetric structure such as turbine rotor by
microcomputer and FEM-BEM method for calculating local
concentrical stresses are presented. The numerical
implementations are correpondly discussed in detail. The
computer programs are developed and used for analysising the
cold start-up procedures of some turbine rotor.
Key words:
