A review of numerical analysis of friction stir welding

open access: yesProgress in Materials Science, 2014
Friction stir welding is a relatively new solid-state joining technique which is widely adopted in different industry fields to join different metallic alloys that are hard to weld by conventional fusion welding. Friction stir welding is a highly complex

Numerical analysis of inflation

Physical Review D, 1985
In this paper the mechanism of a cosmological phase transition is addressed in a new way which avoids weaknesses of previous approaches. The effects of inhomogeneities are included explicitly. A numerical analysis is presented in which for a wide class of models the Universe enters a period of new inflation.

Micromagnetics and Numerical Analysis

Mathematical Models and Methods in Applied Sciences, 1997
The structure of domain walls in ferromagnetic crystals is investigated by means of micromagnetics. Moreover, the numerical integration of one-dimensional micromagnetic equations in domain walls is carried out in order to obtain approximate expressions of the energy associated to these regions.

Microprogramming and Numerical Analysis

IEEE Transactions on Computers, 1971
This short note presents the view that microprogramming affords a technology that can provide a powerful, efficient, and versatile computer facility for numerical analysts. Particular areas of application are discussed. Fundamental questions are raised relevant to the exploitation of this technology by numerical analysts.

Progress in Numerical Analysis

SIAM Review, 1978
Developments in numerical analysis fall into two separate categories. The first comprises work on problems which are unsolved in the sense that either no feasible methods are available or else there is no reliable analysis for the methods which are in use.

Numerical Power Analysis

2001
In this paper we design abstract domains for numerical power analysis. These domains are conceived to discover properties of the following type: "The integer (or rational) variable X at a given program point is the numerical power of c with the exponent having a given property π", where c and π are automatically determined.

Numerical analysis of superposed GSPNs

Proceedings 6th International Workshop on Petri Nets and Performance Models, 1996
The numerical analysis of various modeling formalisms profits from a structured representation for the generator matrix Q of the underlying continuous-time Markov chain, where Q is described by a sum of tensor (Kronecker) products of much smaller matrices.

Numerical Analysis of Bifurcations

1995
In this chapter we shall describe some of the basic techniques used in the numerical analysis of dynamical systems. We assume that low-level numerical routines like those for solving linear systems, finding eigenvectors and eigenvalues, and performing numerical integration of ODEs are known to the reader.

Introduction to Numerical Analysis

2001
Numerical analysis is an increasingly important link between pure mathematics and its application in science and technology. This textbook provides an introduction to the justification and development of constructive methods that provide sufficiently accurate approximations to the solution of numerical problems, and the analysis of the influence that ...
