The TWORNG Code has been used to calculate the thermostructural response of rings that were shock heated by an electron beam. A total of ten experiments were analyzed, covering a range of four materials 6061-T6 aluminum, ATJ graphite, Sandia felt carbon-carbon, and AVCO 3D carbon-carbon. Measured and predicted hoop strains were correlated at several locations on each ring. Several good correlations were obtained, indicating that the basic ingredients of ring thermostructural response are properly understood and are being correctly modeled. Predictions of maximum radial displacements and time-dependent temperature profiles were also generated. To aid interpretation of of the correlations, an approximate closed-form solution for dynamic ring response to in-depth heating was constructed. The approximate solution is limited to linear elastic materials under half cosine load distributions. Author
