Fatigue Life Prediction of Vortex Reducer Based on Stress Gradient
(The American Society of Mechanical Engineers (ASME), 2019)The effects of stress gradient and size effect on fatigue life are investigated based on the distribution of stress at the notch root of notched specimens of GH4169 alloy. The relationship between the life of notched ... -
Treating Epistemic Uncertainty Using Bootstrapping Selection of Input Distribution Model for Confidence-Based Reliability Assessment
(The American Society of Mechanical Engineers (ASME), 2019)Accurately predicting the reliability of a physical system under aleatory uncertainty requires a very large number of physical output testing. Alternatively, a simulation-based method can be used, but it would involve ... -
Expensive Black-Box Model Optimization Via a Gold Rush Policy
(The American Society of Mechanical Engineers (ASME), 2019)The optimization of black-box models is a challenging task owing to the lack of analytic gradient information and structural information about the underlying function, and also due often to significant run times. A common ... -
Comparing the Effects of Design Interventions on the Quality of Design Concepts as a Reflection of Ideation Flexibility
(The American Society of Mechanical Engineers (ASME), 2019)Many tools, techniques, and other interventions have been developed to support idea generation within the design process. In previous research, we explored the separate effects of three such design interventions: teaming, ... -
An Analysis of Modularity as a Design Rule Using Network Theory
(The American Society of Mechanical Engineers (ASME), 2019)Increasing the modularity of system architectures is generally accepted as a good design principle in engineering. In this paper, we explore whether modularity comes at the expense of robustness. To that end, we model three ... -
Over-Design Versus Redesign as a Response to Future Requirements
(The American Society of Mechanical Engineers (ASME), 2019)Though little research has been done in the field of over-design as a product development strategy, an over-design approach can help products avoid the issue of premature obsolescence. This paper compares over-design to ... -
Is Ownership Bias Bad? The Influence of Idea Goodness and Creativity on Design Professionals Concept Selection Practices
(The American Society of Mechanical Engineers (ASME), 2019)Ownership bias is a decision-making bias that leads to an individual's tendency to prefer their own ideas over others' during the design process. While prior work has identified the existence of this ownership bias in ... -
Knowledge-Based Design of Artificial Neural Network Topology for Additive Manufacturing Process Modeling: A New Approach and Case Study for Fused Deposition Modeling
(The American Society of Mechanical Engineers (ASME), 2019)Additive manufacturing (AM) continues to rise in popularity due to its various advantages over traditional manufacturing processes. AM interests industry, but achieving repeatable production quality remains problematic for ... -
Automated Design of Energy Efficient Control Strategies for Building Clusters Using Reinforcement Learning
(The American Society of Mechanical Engineers (ASME), 2019)The control of shared energy assets within building clusters has traditionally been confined to a discrete action space, owing in part to a computationally intractable decision space. In this work, we leverage the current ... -
Understanding the Role of Additive Manufacturing Knowledge in Stimulating Design Innovation for Novice Designers
(The American Society of Mechanical Engineers (ASME), 2019)Additive manufacturing (AM) is recognized as a disruptive technology that offers significant potentials for innovative design. Prior experimental studies have revealed that novice designers provided with AM knowledge (AMK) ... -
Design of a Test Platform for the Determination of Lithium-Ion Batteries State of Health
(The American Society of Mechanical Engineers (ASME), 2019)This paper presents a novel design for a test platform to determine the state of health (SOH) of lithium-ion batteries (LIBs). The SOH is a key parameter of a battery energy storage system and its estimation remains a ... -
Pulling at the Digital Thread: Exploring the Tolerance Stack Up Between Automatic Procedures and Expert Strategies in Scan to Print Processes
(The American Society of Mechanical Engineers (ASME), 2019)While the combination of 3D scanning and printing processes holds much promise for the field of new product development, problems with repeatability and accuracy have limited the wider spread adoption of some digital ... -
Quantifying the Resilience-Informed Scenario Cost Sum: A Value-Driven Design Approach for Functional Hazard Assessment
(The American Society of Mechanical Engineers (ASME), 2019)Complex engineered systems can carry risk of high failure consequences, and as a result, resilience—the ability to avoid or quickly recover from faults—is desirable. Ideally, resilience should be designed-in as early in ... -
Uncertainty Analysis for Time- and Space-Dependent Responses With Random Variables
(The American Society of Mechanical Engineers (ASME), 2019)The performance of a product varies with respect to time and space if the associated limit-state function involves time and space. This study develops an uncertainty analysis method that quantifies the effect of random ... -
Reliability Analysis Using Second-Order Saddlepoint Approximation and Mixture Distributions
(The American Society of Mechanical Engineers (ASME), 2019)This paper proposes a new second-order saddlepoint approximation (SOSA) method for reliability analysis of nonlinear systems with correlated non-Gaussian and multimodal random variables. The proposed method overcomes the ... -
Mass Collaboration Project Recommendation Within Open-Innovation Design Networks
(The American Society of Mechanical Engineers (ASME), 2019)Mass collaboration within the design engineering process supports the inclusion of unique perspectives when working on complex problems. Increasing the number of individuals providing input and support into these perplexing ... -
Investigating User Emotional Responses to Eco-Feedback Designs
(The American Society of Mechanical Engineers (ASME), 2019)Emotional responses to a product can be critical in influencing how the product will be used. This study explores the emotions that arise from users' interaction with eco-feedback products, and investigates links between ... -
Interpreting Idea Maps: Pairwise Comparisons Reveal What Makes Ideas Novel
(The American Society of Mechanical Engineers (ASME), 2019)Assessing similarity between design ideas is an inherent part of many design evaluations to measure novelty. In such evaluation tasks, humans excel at making mental connections among diverse knowledge sets to score ideas ... -
Data-Driven Platform Design: Patent Data and Function Network Analysis
(The American Society of Mechanical Engineers (ASME), 2019)A properly designed product-system platform seeks to reduce the cost and lead time for design and development of the product-system family. A key goal is to achieve a tradeoff between economy of scope from product variety ... -
