ZHENG, Z. L.; LIU, C. Y.; LI, D.  e  ZHANG, T.. Dynamic Response of Orthotropic Membrane Structure under Impact Load based on Multiple Scale Perturbation Method. Lat. Am. j. solids struct. [online]. 2017, vol.14, n.8, pp.1490-1505. ISSN 1679-7825.  https://doi.org/10.1590/1679-78253835.

This paper investigates the dynamic response of rectangular prestressed membrane subjected to concentrated impact load based on multiple scale perturbation method. The governing equations of motion of nonlinear vibration are derived based on the Föppl large deflection theory and Galerkin method. By introducing different time scales to consider the process of vibration, the results of dynamic response are obtained by applying the multiple scale perturbation method. Furthermore, the effects of pretension force, velocity of load and dimension of membrane on the dynamic response of membrane are discussed. The present work studies the problem of the dynamic response of prestressed membrane subjected to concentrated impact load in different time scales, and provides a more accurate theoretical model for design of membrane structure.

Palavras-chave : Membrane structure; dynamic response; nonlinear vibration; multiple scale perturbation method.
