HUGEBOSOR4 is a modified form of BIGBOSOR4. Whereas BIGBOSOR4 will handle up to 295 shell segments, HUGEBOSOR4 will handle up to 2950 shell segments. This increased capacity is especially helpful in computing load factors and mode shapes for the general buckling of truss-core sandwich cylindrical shells and complexly corrugated cylindrical shells such as those shown here. It is expected that HUGEBOSOR4 will be used mainly in connection with GENOPT or in any other context in which valid input files for HUGEBOSOR4 are generated by a computer program or by a subroutine rather than “by hand”.
HUGEBOSOR4 is activated when the user gives the command, "HUGEBOSOR4LOG". The consequently activated command set for HUGEBOSOR4 is the same as that for BIGBOSOR4, but the FORTRAN coding in HUGEBOSOR4 has been modified greatly to expand the capability to analyze multi-segment shells of revolution and multi-segment prismatic shells.
