Workshop 1: State-of-the-Art and Future Instructional and Research Directions in Compliant Mechanism Theory and Design
Workshop #1 - State-of-the-Art and Future Instructional and Research Directions in Compliant Mechanism Theory and Design (One Full Day)
Time: Sunday, September 10, 9am to 12:30pm and 1:30pm to 5pm
Organizers:
Objectives: As the area of compliant mechanism theory and design matures and the interest in this exciting new thrust grows, novel applications increasingly find their way into products used in everyday life and current technologies. Therefore, introspection at this juncture on a vision of the present and future research and education would appear to be most worthwhile. This workshop, presented by a panel of very active researchers and educators, will provide an introductory overview of the origin, the state of the art, potential applications, and promising work in progress in compliant mechanism theory and design. Hands-on demonstration materials and models will be used to elucidate the theories and applications. These presentations will then lead into a much-needed critical discussion of unresolved issues and needs, challenges, and future directions in this field.
Audience: The broad coverage, from introductory to advanced discussions, should make this workshop attractive to those new to the field as well as to experienced design engineers and researchers in compliant mechanisms and interdisciplinary areas. At the conclusion of this workshop, the participants will become well apprised of the state of the art, its potential applications, and its current limitations.

Workshop #2 Uncertainty Representation in Robust and Reliability-Based Design (One Half Day)
Time: Sunday, September 10, 1:30pm to 5pm
Organizers:
- Chris Paredis, School of Mechanical Engineering, Georgia Institute of Technology
- Jason Aughenbaugh, School of Mechanical Engineering, Georgia Institute of Technology
- Zissimos Mourelatos, Mechanical Engineering Department, Oakland University
Objectives and Topics: In this workshop, several different uncertainty representations for robust and reliability-based design will be evaluated and compared. Experienced researchers will present different approaches towards uncertainty representation and decision making under uncertainty, addressing specific criteria for determining the suitability of these representations in the context of design. Such criteria include among others: clarity in the semantics of the uncertainty representation, rigor and consistency of the underlying mathematical formalism, ease of computation, and suitability for decision making.
The intent of the workshop is to spawn a discussion among researchers interested in uncertainty in design - a discussion that focuses on the interpretation of different uncertainty representations and how they can and should be used in support of design decision making. In the current literature, much of the focus in robust and reliability-based design is on improving the computational efficiency of specific analysis and optimization algorithms. As more researchers become interested and involved in this area, it is important that the community does not lose track of the basic concepts and philosophies underlying these algorithms. Currently, little attention is being paid to some of the fundamental philosophical differences that still exist within the community. In this workshop, these different perspectives will be presented, compared, evaluated, and discussed, with the intent to increase awareness and understanding of these sometimes complex issues.
Intended Audience: Researchers, Scholars and students in Robust Design and Design under Uncertainty. The DAC track on Simulation-Based Design under Uncertainty typically draws a large audience; it is anticipated that most of the participant in that track will also be attending this workshop.
Speakers:
- Jason Aughenbaugh: Criteria for comparing uncertainty representations
- Scott Ferson: Probability bounds analysis and imprecise probabilities
- Zissimos Mourelatos: Possibility theory and evidence theory
Materials: Presentation slides will be posted on-line.
Workshop #3 Shape and Topology Optimization: From Theory to Practice (One Half Day)
Time: Sunday, September 10, 1:30pm to 5pm
Organizers:
- Vadim Shapiro (University of Wisconsin)
- Krishnan Suresh (University of Wisconsin)
- Dan Negrut (University of Wisconsin)
Objectives and Topics: Design problems in continuum mechanics naturally give rise to 'shape and topology optimization problems' where the objective is to construct an optimal shape and topology that maximize certain objectives under a set of constraints. The mathematical basis and formulations of such optimization problems is now well known; efficient algorithms and varied applications have also been developed. Indeed, commercial shape & topology optimization packages are readily available, and are often fully integrated with PDE-solvers for ease-of-use. Yet, the impact of this discipline on industrial design is rather limited. The objectives of this workshop are two-fold:
- To review the 'state-of-art' on shape/ topology optimization theory, algorithms and applications, through invited talks.
- To identify technical and non-technical barriers, through panel discussions.
Speakers:
- K. K. Choi (UIowa)
- Jamshid A. Samareh (NASA)
- Vadim Shapiro (UWisconsin)
- Ganesh Subbarayan (Purdue)
- Krishnan Suresh (UWisconsin)
- Jan Vandenbrande (Boeing)
