N2  - Ferrocement beams were tested to investigate the applicability of  elastic-plastic fracture mechanics (EPFM) concepts to ferrocement . The  notched vs. unnotched beam techniques was used to evaluate the J-integral  and the critical crack opening displacement (COD ) approaches. To study c  the influence of different parameters, notch depth, specimen size, and  percentage of. reinforcement were varied. Double cantilever beam (DCB)  specimens were also tested. The results were used to draw the R-curves  showing the influence of different parameters.  J-integral and crack opening displacement (COD) approaches were  found to be independent of notch depths and specimen size. This result  suggests that J-integral and COD are both promising fracture criteria.  R-curves, however, appear to be influenced by notch depth and crackline  thickness, and therefore seem not to be a valid fracture criterion
