Mechanical Analysis for Thin-Walled Stiffened Plates on the Base of Plants Venations Growth Algorithm

Abstract:

The reinforced shin shell structures are widely used in many fields such as mechanical, architecture, aerospace and shipbuilding, etc. The leaf can be seen as shin plate structures with stiffener (vein) and the venation distributions are closed related to the external environment load. Leaf venation growing algorithm is the abstract description of vein growing process and reflects an ideological of learning from nature. This article concerns the mechanical analysis for thin-walled stiffened plates, which consist of static mechanical behavior and dynamic performance. Numerical method is used to analyze three types of plants: non-stiffened plate, traditional stiffened plate and stiffened plate optimized by leaf venations growth algorithm (VGA) method. The calculation results proved that the VGA stiffened plate has better mechanical performances than traditional method and illustrated the effectiveness of the bionic venations layout method for stiffened structures.
