When making design decisions in environmentally benign design and manufacture, the decision maker is often faced with extreme uncertainty. Due to a lack of understanding of the complex dynamics of environmental and societal systems, it is very difficult to judge the impact different design alternatives have on the environment, the economy and the society, especially in the distant future. In th...

The primary target of this project consists of combining the technique of rapid prototyping and casting to produce aluminum parts in a sand mold being made the corresponding models and core boxes by means of the technology of rapid tooling, FDM (fused deposition modeling) of ABS. The followed process to obtain the pieces is casting, that consists of the fused metal spill in a mold pattern previ...

Industrialized production of building components, or entire houses, reduces activities at the construction site to the assembly of parts and has the potential to increase productivity and reduce the design effort invested in every project. However, in order to realize all of the potential efficiency gains that use of predefined components could deliver effective, interoperable information manag...

There are no corresponding CAD education resources for CAD courses for students at colleges and universities. A CAD education resource platform for mechanical design, manufacturing and automation speciality is developed. Feature-based modeling, Pro/TOOLKIT and Family Table provided by Pro/ENGINEER and Visual C++6.0 are utilized to develop three-dimensional standard part resources according to t...

A gradient-index axicon with its initial focus offset from the back surface was designed with the thin-lens approximation. Two samples were fabricated by means of the time-varying boundary condition diffusion method, which is based on the modified quasi-chemical diffusion model. Intensity profile measurements were taken along the focal region of the axicons. The samples produced extended line f...

In order to optimize product designs it is necessary to quickly evaluate many candidate materials in terms of performance and processing costs. Evaluation using physical prototypes yields concrete results but is time intensive and costly when dealing with multiple optimization objectives. As an alternative, computer aided simulation is a reliable means of material evaluation and selection, is i...
