RISLattice Structure Optimization With Orientation-Dependent Material Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Advances in additive manufacturing (AM) techniques have enabled the production of parts with complex internal geometries. However, the layer-based nature of additive processes often results in mechanical properties that ...
Probabilistic Graphical Modeling of Use Stage Energy Consumption: A Lightweight Vehicle Example1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although energy consumption during product use can lead to significant environmental impacts, the relationship between a product's usage context and its environmental performance is rarely considered in design evaluations. ...
Toward a Methodology for Systematically Generating Energy and Materials Efficient Concepts Using Biological Analogies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Energyand materialsefficient designs are highly valued in the context of sustainable product design, but realizing products with significant changes in efficiency is a difficult task. One means to address this challenge ...
A Test Part for Evaluating the Accuracy and Resolution of a Polymer Powder Bed Fusion Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) has many potential industrial applications because highly complex parts can be fabricated with little or no tooling cost. One barrier to widespread use of AM, however, is that many designers ...
Stress-Constrained Design of Functionally Graded Lattice Structures With Spline-Based Dimensionality Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a computationally tractable approach for designing lattice structures for stiffness and strength. Yielding in the mesostructure is determined by a worst-case stress analysis of the homogenization ...
Design Exploration of Reliably Manufacturable Materials and Structures With Applications to Negative Stiffness Metamaterials and Microstereolithography1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the challenges in designing metamaterials for additive manufacturing (AM) is accounting for the differences between as-designed and as-built geometries and material properties. From a designer's perspective, these ...
Multiphysics Design Optimization via Generative Adversarial Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a method for generating concept designs for coupled multiphysics problems by employing generative adversarial networks (GANs). Since the optimal designs of multiphysics problems often contain a combination ...
Additive Manufacturing of Tough Silicone Via Large-Scale, High-Viscosity Vat Photopolymerization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, a large-scale, high-viscosity vat photopolymerization additive manufacturing system is designed and fabricated to print 3D structures as large as 370 × 300 × 370 mm3 out of high-viscosity, low-reactivity ...
Analytical and Experimental Investigation of Buckled Beams as Negative Stiffness Elements for Passive Vibration and Shock Isolation Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The behavior of a buckled beam mechanism, which exhibits both bistability and negative stiffness, is investigated for the purposes of passive shock and vibration isolation. The vibration and shock isolation systems ...
An Experimental Investigation of the Effectiveness of Empathic Experience Design for Innovative Concept Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important part of designing successful products is building empathy for the people for whom the product is intended. Despite recent interest in empathic design techniques, they remain confined primarily to customer needs ...
