A review on computational linear and nonlinear dynamic analysis of shell-type composite structures

Abstract

Composite materials allow the production of structures with desired and improved properties (such as high strength), while minimizing the undesirable outcomes (e.g., increased weight). This ability to tune the properties of materials and structures has put composite materials under the spotlight in many fields, ranging from medical, automotive, aerospace, marine, and civil engineering applications. With the wide range of uses composite materials find their place in, it is important for engineers and researchers to have a good understanding of the behaviors of composite materials, such as bending, buckling, or vibration. As such, in recent years, investigating the dynamical behavior of such structures has been a popular topic of study, as signified by the copious amounts of studies focusing on the linear/nonlinear free vibrational response of these composite/nanocomposite systems. This paper provides a comprehensive review of the available research on nonlinear and linear free vibrations of composite/nanocomposite shell-type structures. The research conducted employs a wide variety of different conditions, geometries, methods/models, and materials. As such, a vast number of unique studies exist, focusing on linear and nonlinear free vibrations of composite/nanocomposite shell-type systems. The goal of this review article is to provide an in-depth summary of the available literature on nonlinear and linear free vibrations of composite/nanocomposite shell-type structures, to elaborate on the methods and approaches used by researchers, to present the findings obtained by researchers regarding this topic so far, and to point out the gap of research with the intention to propel future works of research.
