Manual
:
NASA CR 4686 includes operating instructions. Comments are also included in
electronic form.
Format:
FORTRAN, which may be compiled for target machine.
Geometric
Model:
The binary model consists of line elements to represent the tow axial properties, and
three-dimensional “effective medium” elements to represent the transverse and shear
properties. General configurations of tows can be modeled, but only 3D interlock
weaves are handled automatically.
Stiffness
Model:
The code uses the finite element method. By applying forces or displacements to
various planes, all macroscopic elastic constants can be found. Cyclic symmetry is
not automatically imposed. In addition to the line and 3D elements, there are springs
