摘要：

Single-edge-notched bars are commonly used in materials testing of ceramics for the determination of fracture toughness, For the assessment of the experimental results it is necessary to compute the stress intensity factor of small semi-elliptical cracks at the notch root. A solution for narrow cracks will be provided. (C) 1999 Elsevier Science Ltd. All rights reserved.
