Assessing Lifecycle Value Using Object-Based Modeling by Incorporating Excess and Changeability
(The American Society of Mechanical Engineers (ASME), 2020)Prior research suggests that excess (purposeful inclusion of margin beyond what is required for known system uncertainties) can limit change propagation and reduce system modifications. Reducing change costs increases ... -
Multi-Objective Engineering Design Via Computer Model Calibration
(The American Society of Mechanical Engineers (ASME), 2020)Computer model calibration typically operates by fine-tuning parameter values in a computer model so that the model output faithfully predicts reality. By using performance targets in place of observed data, we show that ... -
Investigation of Parameter Spaces for Topology Optimization With Three-Dimensional Orientation Fields for Multi-Axis Additive Manufacturing
(The American Society of Mechanical Engineers (ASME), 2020)The layer-by-layer deposition process used in material extrusion (ME) additive manufacturing results in inter- and intra-layer bonds that reduce the mechanical performance of printed parts. Multi-axis (MA) ME techniques ... -
Manipulating Users’ Trust of Autonomous Products With Affective Priming
(The American Society of Mechanical Engineers (ASME), 2020)Autonomous products, which perform many functions on their own with limited user input, require users to exhibit trust at an appropriate level before use. Research in product trust has thus far focused on the product ... -
Integrating Sequence Learning and Game Theory to Predict Design Decisions Under Competition
