Abstract Compliant mechanisms (CMs) are used to transfer motion, force, and energy, taking advantages of the elastic deformation involved compliant members. A branch special type phenomenon called (post) buckling has been widely considered in CMs: avoiding for better payload-bearing capacity utilizing post-buckling produce multi-stable states. This paper digs into essence beam’s behaviors where...

Steel plates are used in various structures, such as the structures of the deck and body of ships, bridges, and aerospace industry. In this study, we investigate the buckling and post-buckling behavior of rectangular steel plates having circular cutouts with two boundary conditions: first, clamped supports at upper and lower ends and free supports at other edges; second, clamped supports at upp...

Abstract Owing to their unique material design-ability and excellent weight reduction properties of carbon fibre reinforced polymers(CFRP), commercial aircraft OEMs have been innovating design manufacturing approaches wider the application advanced composites. In this paper, bearing capacity composite hat-stiffened panels is determined by an improved engineering calculation method numerical ana...

Steel plates in double skin composite (DSC) panels are restrained by a concrete core and welded stud shear connectors at discrete positions. Local buckling of steel plates in DSC panels may occur in a unilateral mode between stud shear connectors when subjected to combined states of stresses. This paper studies the local and post-local buckling strength of steel plates in DSC panels under biaxi...

This study investigates geometrical non-linear analysis of composite circular cylindrical shells under external pressure over part of their surfaces and also shells subjected to combined axial compression and triangular external pressure. Donnell non-linear shell theory along with first order shear deformation theory (FOSD) are adopted in the analysis. In the case of combined axial compression ...
