Where is documentation of the stiffness formulation and PSHELL/MAT2 cards?

[HyperSizer User]

Where could I find the methods and equations of output PSHELL MAT2 from
HyperSizer? Can you send/point me where I could find these?

The best references for this are probably in the published AIAA papers on our website.

In particular see these papers...
 
 
Apr 94
  "Thermoelastic Formulation of Stiffened, Unsymmetric Composite Panels for Finite Element Analysis of High Speed Aircraft", 35th AIAA/ASME/ASCE/AHS/ACS Structures, Dynamics, & Materials Conference, Hilton Head, SC, April 1994, AIAA 94-1579

   "Thermomechanical Finite Element Analysis of Stiffened, Unsymmetric Composite Panels With Two Dimensional Models", The 1993 MSC World Users' Conference, Arlington, VA, May 1993, Paper No. 31

 "Stiffness, Thermal Expansion, and Thermal Bending Formulation of Stiffened, Fiber- Reinforced Composite Panels", 34th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, La Jolla, CA, April 1993, AIAA 93-1569 
 
Obviously we have progressed a lot since these papers were written, but the methods described here are basically the same for all panel concepts.
