RISA Visual Representation of Engineering Catalogs Using Variational Autoencoders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Catalogs have been used for over a century for designing engineering systems. While catalogs are excellent repositories of engineering information, they are difficult to navigate and visualize, specifically to spot clusters, ...
Assembly Free Large Scale Modal Analysis on the Graphics Programmable Unit
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Popular eigensolvers such as blockLanczos require repeated inversion of an eigenmatrix. This is a bottleneck in largescale modal problems with millions of degrees of freedom. On the other hand, the classic Rayleigh–Ritz ...
Large Scale Finite Element Analysis Via Assembly Free Deflated Conjugate Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Largescale finite element analysis (FEA) with millions of degrees of freedom (DOF) is becoming commonplace in solid mechanics. The primary computational bottleneck in such problems is the solution of large linear systems ...
Hinge Free Compliant Mechanism Design Via the Topological Level Set
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to introduce and demonstrate a new method for the topology optimization of compliant mechanisms. The proposed method relies on exploiting the topological derivative, and exhibits numerous ...
A Review of Methods for the Geometric Post-Processing of Topology Optimized Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Topology optimization (TO) has rapidly evolved from an academic exercise into an exciting discipline with numerous industrial applications. Various TO algorithms have been established, and several commercial TO software ...
Opportunities and Challenges of Quantum Computing for Engineering Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Quantum computing as the emerging paradigm for scientific computing has attracted significant research attention in the past decade. Quantum algorithms to solve the problems of linear systems, eigenvalue, optimization, ...
A Deflated Assembly Free Approach to Large Scale Implicit Structural Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The primary computational bottleneck in implicit structural dynamics is the repeated inversion of the underlying stiffness matrix. In this paper, a fast inversion technique is proposed by merging four distinct but complementary ...
A Pareto Optimal Approach to Multimaterial Topology Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As additive manufacturing (AM) expands into multimaterial, there is a demand for efficient multimaterial topology optimization (MMTO), where one must simultaneously optimize the topology and the distribution of various ...
A Combinatorial Approach for Constructing Lattice Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lattice structures exhibit unique properties including a large surface area and a highly distributed load-path. This makes them very effective in engineering applications where weight reduction, thermal dissipation, and ...
An Investigation Into the Challenges of Using Metal Additive Manufacturing for the Production of Patient-Specific Aneurysm Clips
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Cerebral aneurysm clips are biomedical implants applied by neurosurgeons to re-approximate arterial vessel walls and prevent catastrophic aneurysmal hemorrhages in patients. Current methods of aneurysm clip production are ...
