A new methodology for the characterization of mode II fracture of pinus pinaste...
Moura, M. F. S. F. de; Silva, M. A. L.; Morais, J. J. L.; Morais, A. B. de; Lousada, J. L.In this study, the End Notched Flexure (ENF) fracture test was used to obtain the mode II Rcurve of the Pinus pinaster wood in the RL crack propagation system. The test method was numerically and experimentally analyzed. In the numerical study, three (3D) and twodimensional (2D) finite element analyses were conducted to determine the mode II critical strain energy release rate (GIIc) and the respective R-curve....
