The current study aims to analyze free and forced vibrations of axially functionally graded
(AFG) Timoshenko beams on two-parameter viscoelastic foundation. In these kinds of …

The present study goals to analyze transient analysis of axially functionally graded (AFG)
Timoshenko beams with variable cross-section. Both the materials and geometrical …

Helical compression springs are known for their linear force-length relation. However, it is
often observed that not ground springs admit a very different mechanical behavior than …

This study is intended to analyze free and forced vibrations of non-uniform composite beams
in the Laplace domain. The free vibration is then taken into account as a special case of …

The objective of this study is to investigate the combined influence of two important topics on
the precision of static and dynamic analyses of non-circular composite helical bars, namely …

In scope of this study, forced vibration analysis of viscoelastic helical rods with varying cross-
section and functionally graded material are investigated. Differential equations governing …

A novel approach is employed in the forced-vibration analysis of functionally-graded annular
structures under conditions of axisymmetry. The material is heterogeneous in the sense that …

The paper presents an efficient numerical method for free vibration analysis of non-uniform
and non-homogeneous cylindrical helices. Power law distribution is used for the variation of …

The dynamic behavior of composite coil springs of arbitrary shape is investigated. The
Timoshenko beam theory is adopted in the derivation of the governing equation. The …

Forced vibration analysis of curved beams on two-parameter elastic foundation subjected to
impulsive loads are investigated. The Timoshenko beam theory is adopted in the derivation …
