Optimization of buckling load for laminated composite plates using adaptive Kriging-improved PSO: A novel hybrid intelligent method

, 2020
An effective hybrid optimization method is proposed by integrating an adaptive Kriging (A-Kriging) into an improved partial swarm optimization algorithm (IPSO) to give a so-called A-Kriging-IPSO for maximizing the buckling load of laminated composite ...

Perilaku Beban-Perpindahan Aksial Pre-Buckling dan Post-Buckling pada Struktur Kolom Elastis

Media Komunikasi Teknik Sipil, 2014
The analysis of column buckling is generally based on the analysis of linear eigenvalue problem to obtain the buckling load. In the linear analysis we do not know the load-displacement behavior especially after buckling occurs.

Decision tree-based machine learning to optimize the laminate stacking of composite cylinders for maximum buckling load and minimum imperfection sensitivity

Composite structures, 2019
Launch-vehicle primary structures like cylindrical shells are increasingly being built as monolithic composite and sandwich composite shells. These imperfection sensitive shells are subjected to axial compression due to the weight of the upper structural
