Abstract This study describes a new method of preform design in multi-stage metal forming processes considering workability limited by ductile fracture. The finite element simulation combined with… Continue Reading
Machining economics problems usually contain highly non-linear equations which may present difficulties for some non-linear programming algorithms. An earlier article by Duffuaa et al.  compared… Continue Reading
While geometric programming is a useful computational approach for engineering design problems, it is often the case that some design variables specifying sizes must be rounded to readily available… Continue Reading
Abstract The dual of a geometric programming problem with negative degree of difficulty is often infeasible. It has been suggested that such problems be solved by finding a dual ‘approximate’… Continue Reading
A dual algorithm applied to a posynomial geometric programming problem generally terminates with a dual feasible solution which is only approximately optimal. The usual methods for recovering the… Continue Reading
This study shows the correlation between the design methodology of the artificial neural network (ANN) and the statistical design of experiments (DOE) approach and is demonstrated for process design… Continue Reading
Abstract This present study considers a body that is divided into rigid zones which interface one another on surfaces of velocity discontinuity and have motions relative to one another on these… Continue Reading
The first part of this paper examines foreign language enrollment statistics from 1960 to 2002 in United States institutions of...
Abstract Geometric programming problems in which several of the variables are restricted to assume either integer values or one of a set of standard sizes are known as Semi-Discrete Geometric… Continue Reading
