摘要:Abstract(#br)In this paper a mixed finite element based on Generalised Beam Theory (GBT) is proposed to analyse the first-order behaviour of naturally curved beams with circular axis (without pre-twist) and having deformable thin-walled cross-sections. The element applies the ass...

摘要:Abstract(#br)In this study, we numerically investigate static and free vibration responses of functionally graded (FG) porous plates with graphene platelets (GPLs) reinforcement using an efficient polygonal finite element method (PFEM). While the bending strain field is approxima...

摘要:Abstract(#br)This paper presents the behavior of fiber-reinforced polymer (FRP)-confined concrete-filled stainless steel tube (CFSST) stub columns under axial loading. Six CFSST stub columns and 18 FRP-confined CFSST stub columns were tested. Typical failure modes and load–d...

摘要:Abstract(#br)To enhance the impacting mechanical performance of the thin-walled structure, this paper proposes three new side fractal structures and investigates their crashworthiness by the experimental testing, simulation analysis and theoretical prediction. The energy absorpti...

摘要:Abstract(#br)The present article proposes an advanced Ritz formulation with 3D capabilities for the analysis of thin-walled metallic and composite beam structures. Various set of admissible functions such as: Legendre, Chebyshev and algebraic polynomials, as well as hybrid functi...

摘要:Abstract(#br)In this paper, the vibrational power flow of a cracked beam made of functionally graded materials (FGMs) is investigated. The Young's modulus and mass density change exponentially along the thickness direction of the beam. The cracked FGM beam is divided into two sub...

摘要:Abstract(#br)This paper investigates the collapse behavior of square paper tubes and the influence of tensile-compressive yield asymmetries of paper tube materials by combining the theoretical and experimental methods. An approximate energy absorption theoretical model is develop...
