摘要：

Spall strength measurements for commerical grade molybdenum and molybdenum single crystals were made in a wide range of load durations (approximately 10(-9) s - 10(-6) s) and intensities (approximately 5 - 100 GPa). Resistance to fracture of pure single crystals was found to exceed two times the spall strength of polycrystalline molybdenum and to increase with shorter load duration. The value-of the shock wave amplitude does not influence the spall strength of single crystals. The largest spall strength obtained under nanosecond load duration amounts to 30% of the ultimate theoretical strength.
