Buckling Behavior of FGM Elastic Arches Subjected to Uniformly Distributed Radial Follow Load

Abstract:

It is assumed that the material properties of arches vary with the thickness direction as a power function. Based on Kirchhoff’s assumption of straight normal line and the theory of axial extension and geometric nonlinearity, the in-plane buckling behavior of FGM elastic arches subjected to uniformly distributed radial follow loads is studied. In this paper, the governing equations for the nonlinear stability of FGM elastic arches are derived, the effect of composition parameters of FGMs, geometric parameters of arches and ends restraints on critical loads and balance configurations is investigated, and corresponding graphs are plotted.
