Abstract:

The results of a two year effort to define and study problems associated with the design of scientific balloons are summarized. These results include the development of a design program including material deformation an analysis program for use in off-design configurations uniaxial and biaxial constant rate testing uniaxial creep testing and uniaxial material characterization. In addition, the need for further investigation is elaborated. Author
