Book Description
Automotive and aerospace components, utensils, and many other products are manufactured by a forming/drawing process on press machines of very thin sheet metal, 0.8 to 1.2 mm. It is imperative to study the effect of all involved parameters on output of this type of manufacturing process. This book offers the readers with application and suitability of various evolutionary, swarm, and bio-inspired optimization algorithms for sheet metal forming processes. Book initiates by presenting basics of metal forming, formability followed by discussion of process parameters in detail, prominent modes of failure, basics of optimization and various bioinspired approaches followed by optimization studies on various industrial components applying bioinspired optimization algorithms. Key Features: • Focus on description of basic investigation of metal forming, as well as evolutionary optimization • Presentation of innovative optimization methodologies to close the gap between those formulations and industrial problems, aimed at industrial professionals • Includes mathematical modeling of drawing/forming process • Discusses key performance parameters, such as Thinning, Fracture, and Wrinkling • Includes both numerical and experimental analysis

Book Description
Analysis and Optimization of Sheet Metal Forming Processes comprehensively covers sheet metal forming, from choosing materials, tools and the forming method to optimising the entire process through finite element analysis and computer-aided engineering. Beginning with an introduction to sheet metal forming, the book provides a guide to the various techniques used within the industry. It provides a discussion of sheet metal properties relevant to forming processes, such as ductility, formability, and strength, and analyses how materials should be selected with factors including material properties, cost, and availability. Forming processes including shearing, bending, deep drawing, and stamping are also discussed, along with tools such as dies, punches, and moulds. Simulation and modelling are key to optimising the sheet metal forming process, including finite element analysis and computer-aided engineering. Other topics included are quality control, design, industry applications, and future trends. The book will be of interest to students and professionals working in the field of sheet metal and metal forming, materials science, mechanical engineering, and metallurgy.

Book Description
Drawing/Forming/Stamping is a compression-tension forming process, which are widely used sheet metal working processes in the industries, to produce cup shaped components at a very high rate. In this process the blank is generally constrained over the draw punch into the die to give required shape of cavity. In drawing the sheet material is subject to a large plastic deformation combined with a complex flow of material. When a metal sheet is deep drawn, the development of wrinkling and a decrease in the limit drawing ratio should be simultaneously suppressed. Blank holder is applied to prevent the wrinkling in the flange & cup wall. Wrinkling is basically initiated by localized buckling due to compressive stresses in circumferential direction. Tensile stress in radial direction causes tearing. Friction coefficient is usually used as a main indicator of friction, which is dependent on material, contact surface and lubricant. Appropriate Punch nose radius & Die profile radius should be selected. The success of process depends upon various parameters and their interactions. It important to understand the influence of all parameters on process output and to optimize them."

Book Description
Numerical simulations of sheet metal forming process based on finite element method (FEM) is widely applied for its powerful capability in forming process prediction. Since there are parameters which could affect the result of forming process, it becomes important to approach a set of parameters to improve the formability. In the present work, first, a comprehensive literature review was made for different optimization methodologies in sheet metal forming process. Then we proposed an optimization methodology using Response Surface methodology (RSM) and Genetic Algorithm (GA) for the optimization of sheet metal forming process, and the theory of RSM and GA are illustrated. The presented method was first applied to an example from literature, the results verified the feasibility of the proposed methodology. Then the methodology was applied to variable binder force optimization of the NUMISHEET 93 2D draw bending problem. The work indicated that the proposed optimization methodology is efficient and universal, which means it can also be applied in other applications of aerospace industry.

Book Description
Through the integration of these features, the current research establishes a framework for design under uncertainty in sheet metal forming. The robust design model takes into account producibility requirements through failure analysis and uncertainties from forming conditions and material properties. The approach was demonstrated through a demonstration example of a wheelhouse stamping process used in automobile industry. In addition, model validation approaches taking uncertainty into account are demonstrated in a simulation of a sample flanging process. Overall, this research presents the methodology and feasibility of implementing the framework for design and optimization under uncertainty, which can certainly be generalized for other industrial cases.
