МКЭ-анализ крутильно-изгибного нагружения бионической несущей структуры, характерной для балтийского региона

Abstract

FEA simulation of the Baltic tree’s bionic load-bearing structure is provided. An array of trees is virtually constructed with heuristic variations in the branch sections and crown shapes. Eccentric wind loads are applied so bending and twisting deformations were simulated. Ironed stress bands (ISB), going along the branch in its middle part, are stated as a steady feature of the tree stress field. The junction between stem and branch becomes free from stress concentration for a wide range of geometry variations. Investigated bionic tree-like forms should be recommended for implementationin the common machinery.
