Abstract:

In order to simplify the analysis of arbitrary stiffeners, Yucheng Liu and Qingkui Wang [1] has proposed a hypothesis called vector analysis of stiffeners, which says that ‘in a stiffened plate following a manner of ‘‘vector analysis’’ based on the geometric features(Figure 1) an arbitrary stiffener can be decoupled into two regular stiffeners’. The study proved this theory with simpler stiffener combinations, but its applications in complicated grid type stiffeners was unknown. This is an FEM analysis with Abaqus which is checking the possibility of extending the applications of vector analysis to complicated stiffener combinations. As a beginning, single units of grid stiffeners like longitudinal, triangular, rectangular and hexagonal are used, and are decouple to equivalent regular stiffeners. The strengthening effects of the single units of grids and its decoupled equivalent combinations were compared. The study proves that the theory is only applicable in simple forms of stiffeners.

Keywords:
