The present paper is devoted to the issue how the critical load of some heterogeneous
beams with three supports can be determined by using Green functions. The stability …

In this paper, optimized shape functions have been used in Rayleigh method to determine
the critical buckling load and the fundamental natural frequency of non-prismatic steel …

Understanding a structure's behavior is necessary for most applications, especially
excitation in ultrasonic applications. Currently, ultrasonic devices are used in various fields …

This paper proposes a simple yet innovative two degrees of freedom (2-DoFs) benchmark
model for structural instability. The proposed rigid-body-spring model is versatile in that it …

Purpose In this work, the concept that defines a spring stiffness is established no longer as a
function of the induced displacement but through the applied force on the system, an …

In this article, the minimum design bending moment of concrete slender columns is studied
by assuming a system of equivalent stiffness. For concrete structural parts such as slender …

The paper continues and discusses the next case of the simplified method of the Technical
Stability Theory (TSTh) of loss of stability of lateral buckling in elastic-plastic states of semi …

Purpose Due to the use of brittle materials and special structure, the porcelain column
electrical equipment is easy to be damaged in the earthquake, so it is necessary to carry out …

Purpose In this paper, the transverse vibrations of an axially moving cantilever beam subject
to a continuously distributed moving mass are studied numerically. Methods An elastic …

There has been an increasing amount of research and applications of hyperelastic bars,
many of which involving beneficial buckling. However, there is limited information available …
