Dynamics of trusses having nonlinear joints [PDF]

The transient analysis of trusses having nonlinear joints can be accomplished using the residual force technique. The technique was applied a two degree of freedom spring mass system, a four bay planar truss, and an actual ten bay deployable truss ...

Impact Dynamics of a Percussive System Based on Rotary-Percussive Ultrasonic Drill

Shock and Vibration, 2017
This paper presents an impact dynamic analysis of a percussive system based on rotary-percussive ultrasonic drill (RPUD). The RPUD employs vibrations on two sides of one single piezoelectric stack to achieve rotary-percussive motion, which improves ...

The strong formulation finite element method: stability and accuracy

Fracture and Structural Integrity, 2014
The Strong Formulation Finite Element Method (SFEM) is a numerical solution technique for solving arbitrarily shaped structural systems. This method uses a hybrid scheme given by the Differential Quadrature Method (DQM) and the Finite Element Method (FEM)

Eigenvalue based inverse model of beam for structural modification and diagnostics: examples of using

Latin American Journal of Solids and Structures
In the work, in order to solve the inverse problem, i.e. the problem of finding values of the additional quantities (mass, elasticity), the beam inverse model was proposed. Analysis of this model allows finding such a value of additional mass (elasticity)
