In the common DR technique, a jump occurs after the appearance of the snap-through or snap-back points. As a result, this approach cannot trace the equilibrium path. To cure this drawback, a load factor is employed. In this paper, a new procedure...

This study is devoted to tracing the equilibrium path of structures with severe nonlinear

behavior. A new displacement increment is suggested to do the analysis. Moreover, the

increment of the load factor is obtained by minimizing...

In this article, functionally graded hollow cylinders with finite length under axisymmetric dynamic loads are analyzed. The dynamic loads applied on the cylinder are axisymmetric in the hoop direction. The governing equations ...

points. All of these valuable features are demonstrated by the equilibrium path, and most of the DR procedures cannot completely trace it. To overcome this weakness, a new variable load factor is presented by minimizing the unbalanced displacement...

This article presents the analysis of functionally graded hollow circular cylinders with finite length under axisymmetric dynamic loads. It is assumed that the functionally graded cylinder is comprised of metal-phase and ...
