This paper presents a novel hybrid FEM-based approach for nonlinear buckling analysis of truss with initial length imperfection. The contribution deals establishing two types finite element (perfection and imperfection element) considering large displacement based on formulation mixed formulation. Therefore, the global equation system is developed by assembling perfection elements. incremental-...

At the initial stage of design, structural strength and stability load-bearing members aircraft are mainly considered. In this paper, a support assembly analyzed. First, analysis, under design load 30.151 KN, numerical analysis shows that, in stress concentration area, peak value is 571.9 Mpa. The experimental strain sensor S6 position compared with results, error within 2.5%, which verifies va...

The whale optimization algorithm (WOA) is a metaheuristic based on swarm intelligence and it mimics the hunting behavior of whales. It has imperfection premature convergence into local optima. In order to overcome this disadvantage, multioperator WOA (MOWOA) proposed. Four main strategies are introduced MOWOA heighten search capacity WOA. include nonlinear adaptive parameter design, an explorat...
