Computational establishment of material design and product design domain integrations: a hybrid approach

Abstract

The present research work is focused on computational establishment of material design and product design integrations- the two major domains of product development strategies. In chapter 2, review over literatures for appropriate material selection in high relevance to product specifications to be plugged in at the early stage of product development has been presented. The scope of the present investigation is presented in chapter 3. Chapter 4 discusses in detail the research methodology adopted in the study. The observed data on results and detailed discussions on the findings of this research work are given in chapter 5. Regression analysis is performed to enhance the dependency facts, as the alloying elements and mechanical property relationships are complex in nature. The results derived through Response Surface Methodology, a module of regression analysis validates and gratifies that the experimental observations are well suited for further proceedings of the research work. In Computational Fluid Dynamics (CFD), the three dimensional valve models are extracted and meshed using the pre-processing software ANSA. Flow investigations for three different fluids viz. water, lubricant oil and diesel at various levels of applicable pressure and temperature is carried over using FLUENT software. Also the results are in good correlation for further proceedings of product structural validation through Finite Element Analysis using ANSYS software. Artificial Neural Network (ANN) structure for feed forward back propagation type of network is developed with 16 inputs (experimental material attributes), 5 outputs (computational product attributes) and an intermediate hidden layer in close context to the adopted domain integration methodology. Successive execution of presented research concept supports in supplying quality product to perform the intended application for the stipulated time span. In chapter 6, major conclusions for the present study and scope for future work are summarized. newline newline newline
