Specimens of Berea Sandstone, Barre Granite, Tennessee Marble, and Valder Limestone were tested at various strain rates under uniaxial tension. The strain rate effect of complete load-deformation curves and the characteristics of fracture propagation under uniaxial tension are illustrated. Contrary to results from uniaxial compression by a servocontrolled test machine, the shapes of the complete load-deformation curves in uniaxial tension varied irregularly with strain rates and ultimate fractures were caused by the coalescence of cracks and advanced cracks in more or less a single plane. Strengths increased with strain rates and fracture could be controlled as in uniaxial compression.
