The report summarizes progress on the analytical and experimental aspects of the investigation concerned with wave propagation resulting from impact on a Yule marble block and an investigation of its mechanical properties. The system was modeled as a transversely isotropic halfspace with the elastic symmetry axis lying in the free surface, loaded by a concentrated normal force of arbitrary time variation. The analysis for the displacements, strains and stresses in the interior is complete and numerical results have been obtained by integral transform methods. A corresponding finite element program has also been completed. Transducer packages for the measurement of stresses in the interior of a Yule marble block have been developed, calibrated and tested. Drilling and embedment techniques for the testing of the Yule marble blocks under actual impact conditions have been evolved. Static and dynamic tests in tension and compression for various orientations of samples have been completed as well as cyclic loading, creep and some fracture tests.
