PANEL ANALYSIS AND SIZING CODE

The Panel Analysis and Sizing Code (PASCO) was developed for the buckling
and vibration analysis and sizing of prismatic structures having an
arbitrary cross section. PASCO is primarily intended for analyzing and
sizing stiffened panels made of laminated orthotropic materials and is of
particular value in analyzing and sizing filamentary composite structures.
When used in the analysis mode, PASCO calculates laminate stiffnesses,
lamina stress and strains (including the effects of temperature and panel
bending), buckling loads, vibration frequencies, and overall panel
stiffness. When used in the sizing mode, PASCO adjusts sizing variables to
provide a low-mass panel design that carries a set of specified loadings
without exceeding buckling or material strength allowables and that meets
other design requirements such as upper and lower bounds on sizing
variables, upper and lower bounds on overall bending, extensional and
shear stiffnesses, and lower bounds on vibration frequencies.

The DEC VAX version of PASCO is written in FORTRAN IV for batch execution
and has been implemented on a DEC VAX series computer. The Macintosh
version of PASCO was developed for Macintosh II series computers with at
least 2Mb of RAM running MPW Pascal 3.0 and Language Systems FORTRAN 2.0
under the MPW programming environment. It includes MPW compatible
makefiles for compiling the source code.
