2021, Thin-Walled StructuresCitation Excerpt :Therefore, the mode-II fracture behavior of adhesively bonded composite joints should be carefully investigated to provide a safe and reliable adhesive joint. Six types of test configuration have been developed for determining the mode-II fracture behavior of composite material or adhesive composite joints: the end-notched flexure (ENF) [8–11], stabilized end-notched flexure (SENF) [12], end-loaded split (ELS) [12,13], four-point end-notched flexure (4ENF) [14–16], over-notched flexure (ONF) [17,18], and tapered end-notched flexure (TENF) [19–21] specimens. Each test configuration has advantages and drawbacks.

2019, Composite StructuresCitation Excerpt :Therefore, proper characterization of the GIIc is then critical for obtaining accurate delamination predictions. A variety of experimental approaches have been proposed in the literature for characterization of the mode II interface fracture, including end-loaded split (ELS) test [10], center-notched flexure (CNF) test [11], end-notched flexure (ENF) test [12], three-point end-notched flexure (3ENF) [13–17] (Fig. 1(a)) and four-point end-notched flexure (4ENF) [18] (Fig. 1(b)), etc. However, with these traditional methods, it is difficult to track the whole development process of GIIc with sufficient accuracy, rather, only the critical SERR or a few discrete data points on the crack-resistance curve can be obtained.
Mixed mode fracture characterization of GFRP-concrete bonded interface using four-point asymmetric end-notched flexure test
2017, Theoretical and Applied Fracture MechanicsCitation Excerpt :Even though ERR can be obtained from the above three typical fracture specimens under different mode mixities, only one crack initiation value can be obtained at a time per specimen because of rapid debonding growth. To overcome the above difficulty, crack steady types of specimens, such as four point end notched flexure (4-ENF) [13], tapered end notched flexural (TENF) [14,15], single contoured cantilever beam (SCCB) [7], and over-leg bending (OLB) [16,17] specimens, were proposed. It has to be mentioned that due to the fact that only bending moments exist within the zone in front of the interface crack tip for the 4-ENF specimen, it was usually deemed that the conventional composite bi-layer beam theory (rigid joint model) would give the same ERRs as those of semi-rigid joint and flexible joint models [18,19].
