HyperSizer HyperSizer was developed from the NASA
Langley Research Center (LaRC) ST-SIZE research code. ST-SIZE was originally developed because NASA identified a need for accurate methods of formulating panel stiffness and thermal expansion coefficients, leading to the development of ST-SIZE from 1988 to 1995. Another need was the reduction of mass on high-speed aircraft and weight reduction for optimization. ST-SIZE was developed by a team of engineers working on the
National Aerospace Plane X-30. Two major versions of ST-SIZE were created. The original version included formulations for stiffness terms and thermal expansion coefficients based on approximations often taken in traditional design methods. In 1990, a version of ST-SIZE was formed for structural design and weight prediction. A new method for formulation of stiffened panel properties was developed starting in 1991. A method for including composite lamina and laminate data in the formulation of stiffened panel structural properties was first developed. Thermal coefficients were created to handle both in-plane and through-the-thickness temperature gradients for membrane, bending, and membrane-bending coupling. A method was then developed to enter these thermal expansion and bending coefficients into the
MSC Software version of
Nastran for
finite element analysis (FEA) using a model with a single plane of finite elements. Other solvers are supported such as
I-DEAS. In May 1996, Collier Research Corporation was formed in
Hampton, Virginia from the original ST-SIZE design team, which included Craig S. Collier. Collier Research obtained an exclusive, all-fields-of-use license, and became the first company to license NASA software for commercial use.

They combined the NASA LaRC ST-SIZE copyright research code with other company proprietary software; the combined software became HyperSizer. ==Uses==
