Motion analysis

In this paper, geometrical nonlinear flutter analysis of functionally graded carbon nanotubes reinforced composite plates is presented. The governing equations of the system are obtained using the Mindlin plate theory and von Karman geometric nonlinearity. The linear piston theory is utilized to determine the aerodynamic pressure. Applying the Hamilton principle, equations of motion of a system are derived in the matrix form, and then the finite element method is used to obtain the discretized equations.

The paper "Nonlinear vibration of functionally graded porous micro-beams resting on elastic foundation" presents the analysis of nonlinear vibration of functionally graded porous (FGP) micro-beams resting on an elastic foundation. The Euler-Bernoulli beam theory (EBT) and the nonlocal strain gradient theory (NSGT) are considered to establish the equations of motion of the micro-beam. The material properties of the micro-beam are assumed to be changed continuously along thickness direction according to simple power-law distribution.

Ebook "Modern charge-density analysis" focuses on state-of-the-art methods and applications of electron-density analysis. It is a field traditionally associated with understanding chemical bonding and the electrostatic properties of matter. Recently, it has also been related to predictions of properties and responses of materials (having an organic, inorganic or hybrid nature as in modern materials and bio-science, and used for functional devices or biomaterials).

In ebook "How do spores select where to settle?: A holographic motility analysis of Ulva zoospores on different surfaces" Matthias Heydt applies digital in-line holography to achieve for the first time a complete three dimensional and real time motion analysis of Ulva zoospores, both in solution and in the vicinity of different surfaces. These results provide previously unknown information about the behavior and mechanism spores use to select a suitable site for settlement. This work gives deeper insight into biofouling algae and stimulates new design strategies for antifouling coatings.

The incidence and mortality rate of rectal cancer are still high, the metastasis of rectal cancer are main causes of death. The control of the distant metastasis is one of the main concerns in the treatment of locally advanced rectal cancer, but there are few studies on predicting synchronous distant metastasis (SDM) of rectal cancer.

We explored a new helical spring magnet (HSM) concept using micromagnetic simulation along with analytical modeling. The present HSMs can be made of a single magnetic material or micro/nano-scale magnetic particles in a polymer matrix, which provides for active control over the motion of the HSMs by additional forces generated by the magnetic interactions inside the HSMs.

This paper presents the finite element algorithm and results on dynamic response of cracked plate structure on elastic foundation subjected to moving oscillator with a constant velocity and any motion orbit. The response to a single moving oscillator is first investigated and then the effects of crack, velocity, elastic foundation stiffness, and stiffness of the spring of moving oscillator are studied.

The size-dependent behavior of a silicon microbeam with an axial force in MEMS is studied using a nonlinear finite element procedure. Based on a refined thirdorder shear deformation theory and the modified couple stress theory (MCST), nonlinear differential equations of motion for the beam are derived from Hamilton’s principle, and they are transferred to a discretized form using a two-node beam element.

In this paper, the authors proposed a higher-order shear deformation theory for buckling and free vibration analysis of functionally graded sandwich plates. Equations of motion derived from Hamilton’s principle are established basing on a refined hyperbolic distribution of transverse shear stress which satisfies the traction free boundary conditions.

In the course of current research the procedure of obtaining of the piecewise linear vibration systems time and frequency responses have been developed. The method is partly analytical and partly numerical and is based on combining of linear solutions of different sections in a cycle of motion. In a row with the method of obtaining of the exact steady state time and frequency response, also it is provided sensitivity analysis of the vibration isolator.
