Papers by Keyword: Requirement Optimization

Abstract: Design engineers can choose from a large variety of materials in order to fulfill a certain function. In those fields of application with a lower level of complexity, it is often sufficient to manufacture the entire component in a “monolithic” manner from one single material. Concurrent, partly contradictory and, most probably, local requirements that must be fulfilled by a component often make material selection more difficult. As a consequence, it is often necessary to use several different materials with a local and functional orientation, which is a part of the multi-material design strategy. The potential of different materials can be used most effectively if this information is made available to the design engineers as early on in the design process as possible. The aim of the SFB 675 sub-project C7, therefore, is the development of a systematic design approach (Finite Element Design, FED) that focuses on finite component elements. As a result, the potential of the optimization of local properties is taken into consideration, and the interaction between the materials, production processes, and design can all be described.

Abstract: New interdisciplinary material and manufacturing technologies make local configuration of material properties possible. The availability of material property information in the early construction process and adequate welding technologies are essential needs to realize a maximum utilization of material. The research objective of two cooperating institutes at the Technical University of Clausthal is to develop a design strategy with related design rules in order to engineer high strength coupling elements of requirement optimized composite materials. Special attention is paid to the usage of future welding technologies and their influence on material properties of locally altered materials. Further objective is an early survey of the consequences caused by the usage of locally altered materials in mixed architecture design projects to the whole production process.
