SUMMARY OF AVAILABLE CODES
8-11
Output:
Plate stiffness matrices, thermal expansion coefficients. Various intermediate
results.
Experimental
Validation
:
Comparisons to measured fabric elastic properties are given in the cited reference.
Comments:
- These codes implement an analysis similar to the classical fabric models, such as
the fiber undulation and bridging models, without some of the simplifying
assumptions used in previous presentations. In principle, the more general
TEXCAD should supersede these earlier isostrain codes. However, the actual
results for plate stiffness are significantly different for the two codes. (See Tables
of results in Section 5.) There appears to be some difference in the way in which
plane stress assumptions are implemented.
- The 2D materials analyzed by these codes would usually be stacked to form a
structure. The stiffness for the stacked laminated must be computed elsewhere.
