直線要素で近似した曲線繊維複合材の作成と評価

Herein, a new method for approximating curvilinear fiber only by linear elements is introduced. The least squares plane is used to simulate curved surface in each region. In this approach, fiber angles in each region is uniquely determined by fixing the boundary line which divides the plate. FRP designed by this method has low production cost and advantage of curvilinear fibers. The proposed methodology is validated by comparing the fundamental frequency of laminated plates having curvilinear reinforcing fibers and approximation model.
