摘      要：This work deals with a description of an elastic analysis of eolic blade （preprocessing, processing and post-processing stages）. The eolic blade geometry is approximated by flat finite elements in which the membrane effects are evaluated using the FF （free formulation） finite element and the flexure effects are calculated using DKT （discrete shear triangle） finite element. The pre-processing stage is implemented using OpenGL library, to provide the graphical construction for geometry, mesh orientation, and other requirements of the finite element model. For the processing stage is built a specific dll （dynamic link library） library implemented in C＋＋ language for the FF and DKT elements analysis. The post-processing stage has been built using specific dialogs to present all results in the graphic interface, where the static displacements of the eolic blade model are shown.
