TL;DR: In this paper, a nonlinear multidegree-of-freedom (mdof) model of bladed disk system is analyzed in frequency domain by applying a quasi-linearization technique, which transforms the nonlinear differential equations into a set of nonlinear algebraic equations.

TL;DR: In this article, a two-dimensional microslip friction model with normal load variation induced by normal motion is presented, which characterizes the stick-slip-separation of the contact interface and determines the resulting friction force, including its time variance and spatial distribution, between two elastic structures.

TL;DR: In this paper, a forced response prediction method for the analysis of constrained and unconstrained structures coupled through frictional contacts is presented, where discrete contact points along with contact stiffnesses are distributed on the friction interfaces.

TL;DR: In this paper, a modified couple stress theory based approach of analysis for small-scale functionally graded beams, that possess a variable length scale parameter, is proposed, which is capable of predicting static and dynamic beam responses according to three different beam theories.

TL;DR: In this article, a one-dimensional dynamic microslip friction model, including the damper inertia, is presented, and an analytical approach is developed to obtain the steady-state solution of the resulting nonlinear partial differential equations when subjected to harmonic excitation.
