RISRoof Deformation and Collapse of Stamps With Isolated Grooves: A Contact Mechanics Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper has revisited the roof deformation and collapse of stamps with isolated grooves based on a contact mechanics approach, with emphasis on establishing the nonadhesive and adhesive contact solutions for surfaces ...
Plane Contact and Partial Slip Behaviors of Elastic Layers With Randomly Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A plane contact and partial slip model of an elastic layer with randomly rough surface were established by combining the Greenwood–Williamson (GW) rough contact model and the Cattaneo–Mindlin partial slip model. The ...
Thermoelastic Coupling Vibration Characteristics of the Axially Moving Beam With Frictional Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermoelastic coupling vibration characteristics of the axially moving beam with frictional contact are investigated. The piecewise differential equation of motion for the axially moving beam ...
Doing Topology Optimization Explicitly and Geometrically—A New Moving Morphable Components Based Framework
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, we intend to demonstrate how to do topology optimization in an explicit and geometrical way. To this end, a new computational framework for structural topology optimization based on the concept of ...
A Unified Treatment of Axisymmetric Adhesive Contact on a Power Law Graded Elastic Half Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present paper, axisymmetric frictionless adhesive contact between a rigid punch and a powerlaw graded elastic halfspace is analytically investigated with use of Betti's reciprocity theorem and the generalized Abel ...
Revisiting the Maugis–Dugdale Adhesion Model of Elastic Periodic Wavy Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The plane strain adhesive contact between a periodic wavy surface and a flat surface has been revisited based on the classical Maugis–Dugdale model. Closedform analytical solutions derived by Hui et al. [1], which were ...
Lagrangian Description Based Topology Optimization—A Revival of Shape Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unlike in the previous treatment where shape and topology optimization were carried out essentially in an Eulerian framework, the aim of the present work is to show how to perform topology optimization based on a Lagrangian ...
Plane Contact and Adhesion of Two Elastic Solids With an Interface Groove
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A systematic study is performed on the plane contact and adhesion of two elastic solids with an interface groove. The nonadhesion and Johnson–Kendall–Roberts (JKR) adhesion solutions for a typical groove shape are obtained ...
A New Uncertainty Analysis-Based Framework for Data-Driven Computational Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, a new uncertainty analysis-based framework for data-driven computational mechanics (DDCM) is established. Compared with its practical classical counterpart, the distinctive feature of this framework is ...
Exploring Elastoplastic Constitutive Law of Microstructured Materials Through Artificial Neural Network—A Mechanistic-Based Data-Driven Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a data-driven approach for constructing elastoplastic constitutive law of microstructured materials is proposed by combining the insights from plasticity theory and the tools of artificial intelligence (i.e., ...
