摘要：

Mixed-mode fracture characteristics of plain concrete and concrete with 0.3% volume fraction of polypropylene and steel fibers were investigated experimentally Different test configurations and notch locations were used. The test results were interpreted using linear and nonlinear fracture mechanics concepts. Nonlinear fracture parameters appropriately described the positive effects of low volume fractions of fibers on the mixed-mode fracture characteristics of concrete. The results help assess the effectiveness of fibers in controlling the opening and slippage of cracks. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
