Abstract:

Report documents a 14-month program conducted to study the parameters of crack growth in viscoelastic materials. Tests conducted on Solithane and a filled propellant are described, and results of the experimental effort are presented. Analysis of data through the concepts of viscoelastic fracture mechanics is discussed. The behavior of cracks in solid rocket motor geometries and of propellantliner unbonds was monitored in unique test situations. Basic analytic concepts were compared with test data and found to show promise of applicability. Recommendations for expansion of the study are presented.
