Pseudotsuga menziesii ((Mirb.) Franco) in Portugal: A Review of Species Charact...
Fonseca, Teresa Fidalgo; Silva, M. E.; Lousada, J. L.; Luis, J. S.; Gonçalves, Ana CristinaPseudotsuga menziesii ((Mirb.) Franco), known as Douglas fir, is a prominent conifer species native to North America. It is known for its adaptability, rapid growth, and high-quality wood. It was introduced to Europe in the nineteenth century and is currently the most abundant non-native tree species cultivated in Central European forests. In Portugal, the species was initially cultivated as an ornamental plant...
Experimental and numerical analyses of wood boards joining using wood-pin conne...
Dourado, N.; Pereira, F. A. M.; Lousada, J. L.; Moura, M. F. S. F. deThis paper addresses the joining of two wood boards considering bonding and wood pins connections. Experimental tests involving these two assemblies were performed. Four different inclinations were con- sidered for the four pins in order to assess the influence of this parameter on stiffness and strength of the joint, which were compared with the bonded solution. A three-dimensional finite element analysis includ...
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....
