This is a summary of my over 15 years work as a mechanical design engineer in electronics industry. The contents include: · The task, design considerations, developing steps of mechanical design for electronics product. · The frequent using mechanical components design guideline. · Specific function design, such as seal, EMC, screw torque definition and calculation. · Tolerance analysis. · Preliminary thermal distribution design. · Other topics such as DFM, failure root cause analysis, etc. Components design guideline is the major part of this book. The components are categorized according manufacturing method, such as sheet metal, plastic injection, die casting, Aluminium extrusion, over mold, rubber keypad and standards components selection. In each individual guideline, the typical structure is used to include the main items of: · Characters about advantages and disadvantages. · Brief description of typical manufacturing process and related equipment. · Frequent using material. · Structure design considerations. · Typical features. · Tolerance. · Frequent defects and analysis. The aim of this book is to provide guide and support to the junior mechanical design engineers in electronics industry, and I assume the readers have mechanical knowledge and reasonable design practise. So I excluded the massive basics that can be found from popular manuals or standards to make the book brief and wish could bring the readers practical help.

In the coming decades, the growth in AM will likely be driven by production parts that leverage this increase in design freedom to manufacture parts of higher performance and improved material utilization. Contrary to popular opinion, however, AM processes do have their constraints and limitations - not everything can be manufactured with AM, and even when it is feasible, not everything should. Design for Additive Manufacturing: Concepts and Considerations for the Aerospace Industry, edited by Dr. Dhruv Bhate, is a collection of ten seminal SAE International technical papers, which cover AM from the perspective of the appropriateness (should) and feasibility (can) of using AM for manufacturing of parts and tooling. Although AM technologies have been around for three decades, many in the industry believe that we are merely at the beginning of the revolution in the design-driven aspects of this technology. Indeed, half the papers in this selection were published only in the past two years, and all but one in the past decade. When it comes to design for AM, it is a safe bet that the best is yet to be.

Taking a failure prevention perspective, this book provides engineers with a balance between analysis and design. The new edition presents a more thorough treatment of stress analysis and fatigue. It integrates the use of computer tools to provide a more current view of the field. Photos or images are included next to descriptions of the types and uses of common materials. The book has been updated with the most comprehensive coverage of possible failure modes and how to design with each in mind. Engineers will also benefit from the consistent approach to problem solving that will help them apply the material on the job.

The broad use of composite materials and shell structural members with complex geometries in technologies related to various branches of engineering has gained increased attention from scientists and engineers for the development of even more refined approaches and investigation of their mechanical behavior. It is well known that composite materials are able to provide higher values of strength stiffness, and thermal properties, together with conferring reduced weight, which can affect the mechanical behavior of beams, plates, and shells, in terms of static response, vibrations, and buckling loads. At the same time, enhanced structures made of composite materials can feature internal length scales and non-local behaviors, with great sensitivity to different staking sequences, ply orientations, agglomeration of nanoparticles, volume fractions of constituents, and porosity levels, among others. In addition to fiber-reinforced composites and laminates, increased attention has been paid in literature to the study of innovative components such as functionally graded materials (FGMs), carbon nanotubes (CNTs), graphene nanoplatelets, and smart constituents. Some examples of smart applications involve large stroke smart actuators, piezoelectric sensors, shape memory alloys, magnetostrictive and electrostrictive materials, as well as auxetic components and angle-tow laminates. These constituents can be included in the lamination schemes of smart structures to control and monitor the vibrational behavior or the static deflection of several composites. The development of advanced theoretical and computational models for composite materials and structures is a subject of active research and this is explored here for different complex systems, including their static, dynamic, and buckling responses; fracture mechanics at different scales; the adhesion, cohesion, and delamination of materials and interfaces.
