RISDesign and Manufacturing Functionally Gradient Material Objects With an Off the Shelf Three Dimensional Printer: Challenges and Solutions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the challenges and solutions encountered while designing and then printing functionally gradient material (FGM) objects using an off the shelf fused deposition modeling (FDM) 3D printer. The printer, ...
Optimizing Topology and Gradient Orthotropic Material Properties Under Multiple Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goal of this research is to optimize an object's macroscopic topology and localized gradient material properties (GMPs) subject to multiple loading conditions simultaneously. The gradient material of each macroscopic ...
Uncertainty Quantification of a Machine Learning Model for Identification of Isolated Nonlinearities With Conformal Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Structural nonlinearities are often spatially localized, such joints and interfaces, localized damage, or isolated connections, in an otherwise linearly behaving system. Quinn and Brink (2021, “Global System Reduction Order ...
Uncertainty-Aware, Structure-Preserving Machine Learning Approach for Domain Shift Detection From Nonlinear Dynamic Responses of Structural Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex structural systems deployed for aerospace, civil, or mechanical applications must operate reliably under varying operational conditions. Structural health monitoring (SHM) systems help ensure the reliability of ...
Design of a Single Layer Metamaterial for Pressure Offloading of Transtibial Amputees
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: While using a prosthesis, transtibial amputees can experience pain and discomfort brought on by large pressure gradients at the interface between the residual limb and the prosthetic socket. Current prosthetic interface ...
