An Alternative Approach of Initial Stability Analysis of Kirchhoff Plates by the Boundary Element Method

Engineering Transactions, 2014
An initial stability of Kirchhoff plates is analysed in the paper. Proposed approach avoids Kirchhoff forces at the plate corner and equivalent shear forces at a plate boundary. Two unknown variables are considered at the boundary element node.
