Abstract
An analytical and experimental investigation of mode I (tensile and mixed mode (combined tensile and shear) fracture of concrete subjected to impact loading was conducted. The rate of loading ranged from slow strain rate of 10-6 per second to impact strain rate of 0.5 per second. Mixed mode tests were conducted using beams with notches at different locations along the span of the beam. A modified Charpy instrumented impact testing system was used to obtain impact test results. A new clip gage was developed to measure crack opening displacements at slow and impact rates of loading. A nonlinear fracture mechanics model was developed to predict the rate sensitivity of mode I and mixed mode fracture of concrete. Additional aspects of the subject are discussed.
