First Order Approximation Approach toward Welding Design Optimization : Preliminary Study

概要

論文の詳細を見る
It is pointed out in this paper that first order approximation technique might be one of the most convenient and effective technique to solve decision-making problems related to optimization of welding conditions in design and fabrication. Although most of the decision-making problems encountered in welding are those of discrete variables, only few techniques are available to solve such discrete variable problems. First order approximation technique described herein is considered to be one of the simplest and have wide applicability, and the case of decreasing stress concentration factor in a cruciform welded joint subjected to bending is described by way of illustration of the effectiveness of this approach.
