Nonlinear dynamic analysis of beams with layered cross sections under moving masses

Abstract This paper considers the nonlinear dynamic analysis of moving masses applied on beams with layered cross sections. This mechanical system is often used in passenger transportation systems, such as high-velocity trains and magnetic levitation transport vehicles. The structural systems are modeled numerically with the aid of a formulation based on the Finite Elements Method. The main objective of this paper was to present an original numerical approach for a mass-beam system using the concept of positional geometric nonlinearity, which uses nodal positions rather than nodal displacements to describe the finite elements kinematics. By using this methodology, analyses can be performed for moving masses traveling with constant or variable velocity in dimensionless or physical problems. For the analyzed problems, sets of results are presented for the mechanical behavior analyses, such as the moving mass trajectories along the mass-beam coupled system. Moreover, a comparative study is performed on beams with rectangular and rail cross sections. After the passage of the moving masses, the elastoplastic rectangular cross-sectional beam presents a higher stiffness than the elastoplastic rail cross-sectional beam, as a result of the double plasticity that occurs at the extreme surfaces. Another original numerical example presents a beam made of two different materials under the action of a moving mass.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
