摘要

摘要利用精细的剪切变形理论,对叠层直梁的静力变形进行了分析,已有大量的研究文章。然而,目前对具有简支边界条件的叠层曲梁变形的研究是有限的,需要更多的关注。为此,本研究采用一种新的准三维多项式型梁理论,对立面弯曲的叠层复合材料梁和夹层梁进行了静力分析。该理论考虑了横向剪切和法向应变的影响,即厚度拉伸效应。在目前的理论中,轴向位移已经扩展到厚度坐标的五阶多项式,以有效地考虑曲率和变形的影响。该理论满足梁上下表面的零牵引边界条件。利用虚功原理建立了控制微分方程及其边界条件。Navier的求解技术用于获得在高程上弯曲并受到均匀分布载荷的简支梁的位移和应力。目前的研究结果可以为即将到来的研究人员带来好处。

On the deformation of laminated composite and sandwich curved beams
Abstract Plenty of research articles are available on the static deformation analysis of laminated straight beams using refined shear deformation theories. However, research on the deformation of laminated curved beams with simply supported boundary conditions is limited and needs more attention nowadays. With this objective, the present study deals with the static analysis of laminated composite and sandwich beams curved in elevation using a new quasi-3D polynomial type beam theory. The theory considers the effects of both transverse shear and normal strains, i.e. thickness stretching effects. In the present theory, axial displacement has expanded up to the fifth-order polynomial in terms of thickness coordinates to effectively account for the effects of curvature and deformations. The present theory satisfies the zero traction boundary condition on the top and bottom surfaces of the beam. Governing differential equations and associated boundary conditions are established by using the Principal of virtual work. Navier’s solution technique is used to obtain displacements and stresses for simply supported beams curved in elevation and subjected to uniformly distributed load. The present results can be benefited to the upcoming researchers.

期刊介绍: The aim of Curved and Layered Structures is to become a premier source of knowledge and a worldwide-recognized platform of research and knowledge exchange for scientists of different disciplinary origins and backgrounds (e.g., civil, mechanical, marine, aerospace engineers and architects). The journal publishes research papers from a broad range of topics and approaches including structural mechanics, computational mechanics, engineering structures, architectural design, wind engineering, aerospace engineering, naval engineering, structural stability, structural dynamics, structural stability/reliability, experimental modeling and smart structures. Therefore, the Journal accepts both theoretical and applied contributions in all subfields of structural mechanics as long as they contribute in a broad sense to the core theme.
