摘要: Abstract A high precision finite element has been derived for large deflection and post-buckling analysis of thin arches arbitrary shapes. Emphasis is placed on accurate representation geometry at all stages deformation. This approach ensures natural rigid body modes, which crucial integration equation motion through the critical points. Full non-linear expressions are retained to account objectivity interaction between axial force bending moment.
