โœฆ Synopsis

An experimental investigation was conducted to examine how the upper stress intensity factor in parallel shear KrrrQ (similar to KrQ for Mode I) is affected by increasing the tensile strength of a material. Round notched and precracked bar specimens, fabricated from 4340 steel were used for the investigation. Based on results from four different heat-treatments of this steel it was found that the stress intensity factor KrIm increases as the tensile strength increases. Values of I&Q obtained for high strength 4340 steel are in a~eement with those found by other investigators.

Fracture properties and fracture behavior of concrete under dynamic loadings are investigated. Several series of concrete beams were tested under various rates of loadings. The relative initial notch depths of test beams were varied from zero to 0.75. The loaddeflection curves and the corresponding

models are proposed to predict the mixed-mode fracture of notched composite laminates subjected to uniaxial and multiaxial loading. The basic elastic, strength properties and a characteristic length are utilized by these models. The characteristic length is determined differently for the two models.
