In this study, an extended stress-based forming limit diagram (FLD) for prediction of necking based on the Marciniak and Kucznski (M-K) model is represented and applied in tube hydroforming. The bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. This adaptive simulation technique is based on the ability to detect the onset and growth of defects (e.g., bursting and wrinkling) and to promptly readjust the loading paths. Thus, a suitable load path is determined by applying Adaptive Simulation Method in ANSYS Parametric Design Language (APDL).

Connecting Design Problem Characteristics to Prototyping Choices to Form a Prototyping Strategy Abstract Prototyping is a critical part of the product design process with the potential to play a significant role in determining the success or failure of the product. A variety of decisions are made by the design team when determining the manner in which they will develop prototypes. Example decisions include: choosing to develop either multiple prototypes or only a single prototype; and choosing to develop either a scaled or fully functional prototype. We define a prototyping strategy as the compilation of all the decisions that need to …

Physical Models in Engineering Education: Making Tomorrow’s Designers Creative Innovation and creativity are two essential qualities for tomorrow’s designers. In order to nurture these skills in designers, our engineering curricula need to include more hands-on training. In recent times, many engineering educators have recognized the importance of hands-on training in engineering curriculum. Allowing students to build and test their own physical models and learn from their mistakes can be a very effective way of teaching. Recent studies have shown that physical models play a very important role in design innovation and creativity. Building and testing such models can lead designers …
Examining Design Fixation In Engineering Idea Generation: The Role Of Example Modality, Vimal Viswanathan, Julie Linsey
Examining Design Fixation In Engineering Idea Generation: The Role Of Example Modality, Vimal Viswanathan, Julie Linsey
Faculty Publications, Mechanical Engineering
Design fixation is a major concern in engineering idea generation because it restricts the solution space in which designers search for their ideas. For designers to be more creative, it is essential to mitigate their fixation. The majority of studies in the literature investigate the role of pictorial stimuli in design fixation; however, the role of examples presented in other formats, including physical prototypes, is largely unknown. This paper presents a study that compares design fixation, in novice designers, caused by pictorial and physical representations. The effects of defixating materials proposed by Linsey et al. (2010) are also investigated. The …
