Fracture Behavior of Ferrocement Beams
Publication: Journal of Structural Engineering
Volume 112, Issue 7
Abstract
An attempt is made to study the fracture behavior of ferrocement beams using J‐integral and critical crack opening displacement approaches. Ferrocement beams with three different relative notch depths and different percentages of mesh reinforcement were tested in four‐point bending (third‐point loading). The experimental results were used to evaluate the apparent J‐integral and values. Results show that the apparent J‐integral does not seem to follow any particular trend in variation with notch depth, but is sensitive to the increase of mesh reinforcement. Hence, the apparent J‐integral appears to be a useful fracture criterion for ferrocement. The computed values of CODt are found to be dependent on the depth of notch and, thus, cannot possibly be considered as a suitable fracture criterion for ferrocement.
