Abstract: The cyclic stress-strain response of S960 at the toe of fillet-welded joint has been simulated by means of finite element method in order to gathering the needed data for fatigue life prediction process. The Femap software (Version 11.0.0) with NX Nastran 8.5 as its solver has been used in this simulation work. Since the special emphasis is on analyzing the cyclic behavior of weld toe and the softening effect on its cyclic behavior, for making a more accurate and realistic simulation, the 3D finite element model has been analyzed in two different categories: homogeneous (no softening) and inhomogeneous (with softening). The final cyclic stress-strain curve (CSSC) based on the stress and strain changes at weld toe for both cases have been obtained and compared

Abstract: Sharing the product information between the product development members has been important due to the product diversification and complication. Quality Function Deployment (QFD) is an effective method to share the information of the product via the quality matrices that describes the relationship between design elements needed to be considered. This paper improves QFD by applying the Interpretive Structural Modeling (ISM) that visually expresses the complex relationship between them. The proposed QFD was applied to a head protection wear design problem.
