“…Based on a centralized computer-aided design product model, simulation models can be derived with proper simplifications and assumptions. However, a one-way mapping that governs changes from CAD models to simulation models must be established for rapid simulation model updates (Chang et al, 1998a). The mapping maintains consistency between CAD and simulation models throughout the product development cycle.…”

“…Critical plane method, which is sophisticated but more general, is usually employed for computing fatigue life under multi-axial stresses [27]. The strain-based approach is demonstrated (Figure 8) using a lower control arm of the High Mobility Multipurpose Wheeled Vehicle (HMMWV) with experimental validation [28].…”

SUPPLEMENTARY NOTES ABSTRACTIn this research, a systematic reverse engineering, re-engineering, and fast manufacturing (RRF) process has been developed and validated. Commercial off-the-shelf (COTS) software tools and equipment that support the RRF process have been identified, evaluated, and tested. An integration framework has also been developed and employed to create an RRF testbed. This testbed constructed using COTS software and equipment supports three major engineering tasks: the reverse engineering that supports recovering of technical data from worn sample parts, re-engineering that alters design for better performance or lower cost, and fast prototyping that incorporates advanced manufacturing technologies to produce functional or physical prototype of the part in small quantity in a short turnaround time. The primary objective of the project is to develop a systematic, accurate, and efficient re-engineering and prototyping technology for fatigue and fracture of mechanical parts and subsystems, especially due to impact loads, for both military and industrial applications. The goals are to demonstrate such a technology, to support Oklahoma City Air Logistics Center (OC-ALC) to establish similar integrated system in the near future, and to assist OC-ALC to gradually build up expertise to adequately tackle the fatigue and fracture problems. Ultimately, the system developed in the proposed research will support OC-ALC engineers to re-engineer and manufacture quality parts and subsystems that enhance reliability of the aging fleets, therefore, overcoming the new challenge and successfully accomplishing OC-ALC's missions.In this research, a systematic reverse engineering, re-engineering, and fast manufacturing (RRF) process has been developed and validated.

“…Model-based information management has much more extensive use in automotive design and naval architecture than in construction, and hence knowledge gained from these will definitely have an influence on some future trends, bringing forward solutions to architecture as well. Model-related issues and so-called simulation-based design (SBD) have been an active research area within naval architecture (Baum et al 1997;Chang et al 1998).…”

Abstract. This paper examines the meaning of information and communication technology (ICT) for architectural design in early design project phases, with a particular interest in building information modelling (BIM). Contemporary digital design environment, research context and objectives are first clarified, followed by the presentation and analysis of a few BIM-related projects. A key finding is that the architectural working environment, the design methods and the designer's roles have changed in the contemporary project context. Furthermore, other methods and tools are needed in addition to BIM in the early project phases, because it can not solve all required design aspects. [The presentation is part of the author's post-graduate studies in architectural BIM].
