This chapter covers the numerical modeling of carbon nanotubes based on the finite element method. The approach based on a three-dimensional space-frame structure where the bonds between carbon atoms are considered as connecting load-carrying generalized beam members, while the carbon atoms act as joints of the members, is introduced. The assignment of

A finite element model for ultrasonic cutting
Ultrasonics, 2006Using a single-blade ultrasonic cutting device, a study of ultrasonic cutting of three very different materials is conducted using specimens of cheese, polyurethane foam and epoxy resin. Initial finite element models are created, based on the assumption that the ultrasonic blade causes a crack to propagate in a controlled mode 1 opening, and these are ...

Schwinger model on a finite-element lattice
Physical Review D, 1988The mass gap in the Schwinger model is calculated directly using a method which involves expansion in the lattice spacing. On the lattice the mass in the model is given by ..mu../sup 2/ = e/sup 2//M sin(..pi../M), where M is the number of spatial lattice sites. Current correlation functions and matrix elements are also examined.

Many structures of practical importance are too complex to be analyzed by classical, analytical techniques and, hence, numerical analysis is generally used. The finite element method is the most widely used numerical technique for structural and system analyses.

A FINITE ELEMENT MODEL FOR ACOUSTIC RADIATION
Journal of Sound and Vibration, 1998Summary: An extension of the finite element technique to the analysis of the acoustic radiation is presented. In the proposed approach, the acoustic domain is split into two parts by an arbitrary artificial boundary enclosing the radiating surface. Then the unbounded medium is discretized with finite elements consisting of only one or two rows in the ...

The finite element method is nowadays the standard method for solving partial differential equations, especially in continuum mechanics. In this chapter the fluid, solid and interface elements are derived. The elements are employed for the discretization of the nearfield, that is the dam, the nearfield of the foundation and the nearfield of the ...

Finite Element Modelling of the Flange Cleats
2013Most important component of the bolted beam to column joints with the flange cleats is the angle cleat in bending (tension zone). Numerical simulation of the angle cleat in bending is complicated problem primary because of its three di-mensional (3D) nature. In addition, the non- linear phenomena’s, such are the ma-terial and geometrical nonlinearities,
