Edge Notch

A theoretical buckling load for a strut with a single-edge notch at its mid point is calculated assuming that the effect of the notch is to produce a discontinuity in the slope of the strut. This buckling load is not likely to be reached if the material of the strut is at all brittle and it is shown that the fracture load can be calculated from the critical stress intensity factor of the material. Some justification to the theoretical treatment is obtained from the analysis of previous experimental results.

Abstract The critical stress intensity factor of mode I (K Ic) obtained by compact tension (CT) tests of wood and medium-density fiberboard (MDF) was experimentally and numerically analyzed. A double cantilever beam (DCB) test was also conducted and the results were compared with those of the CT tests. Similar to the results of single-edge-notched bending (SENB) and single-edge-notched tension (SENT) tests previously conducted, the value of K Ic was obtained properly from the CT test when an additional crack length was taken into account.
