Dynamics and Control of Global Instabilities in Open-Flows: A Linearized Approach
Applied Mechanics Reviews - Tập 63 Số 3 - 2010
Denis Sipp, Olivier Marquet, Philippe Méliga, Alexandre Barbagallo
This review article addresses the dynamics and control of low-frequency unsteadiness, as observed in some aerodynamic applications. It presents a coherent and rigorous linearized approach, which enables both to describe the dynamics of commonly encountered open-flows and to design open-loop and closed-loop control strategies, in view of suppressing or delaying instabilities. The approach i...... hiện toàn bộ
Mechanics and thermodynamics of saturated/unsaturated porous materials and quantitative solutions*
Applied Mechanics Reviews - Tập 55 Số 4 - Trang 351-388 - 2002
BA Schrefler
Models for thermo-hydro-mechanical behavior of saturated/unsaturated porous media are reviewed. The necessary balance equations are derived using averaging theories. Constitutive equations are obtained using the Coleman-Noll procedure and thermodynamic equations for the model closure are introduced. A particular form of the governing equations is then solved numerically and the numerical p...... hiện toàn bộ
Cohesive Zone Models: A Critical Review of Traction-Separation Relationships Across Fracture Surfaces
Applied Mechanics Reviews - Tập 64 Số 6 - 2011
Kyoungsoo Park, Gláucio H. Paulino
One of the fundamental aspects in cohesive zone modeling is the definition of the traction-separation relationship across fracture surfaces, which approximates the nonlinear fracture process. Cohesive traction-separation relationships may be classified as either nonpotential-based models or potential-based models. Potential-based models are of special interest in the present review article...... hiện toàn bộ
On the Role of Nonlinearities in Vibratory Energy Harvesting: A Critical Review and Discussion
Applied Mechanics Reviews - Tập 66 Số 4 - 2014
Mohammed F. Daqaq, Ravindra Masana, Alper Ertürk, D. Dane Quinn
The last two decades have witnessed several advances in microfabrication technologies and electronics, leading to the development of small, low-power devices for wireless sensing, data transmission, actuation, and medical implants. Unfortunately, the actual implementation of such devices in their respective environment has been hindered by the lack of scalable energy sources that are neces...... hiện toàn bộ
Continuum Modeling for Repetitive Lattice Structures
Applied Mechanics Reviews - Tập 41 Số 7 - Trang 285-296 - 1988
Ahmed K. Noor
The status and some recent developments of continuum modeling for repetitive lattice structures are summarized. Discussion focuses on a number of aspects including definition of an effective substitute continuum; characterization of the continuum model; and the different approaches for generating the properties of the continuum, namely, the constitutive matrix, the matrix of mass densities...... hiện toàn bộ
Lattice models in micromechanics
Applied Mechanics Reviews - Tập 55 Số 1 - Trang 35-60 - 2002
Martin Ostoja–Starzewski
This review presents the potential that lattice (or spring network) models hold for micromechanics applications. The models have their origin in the atomistic representations of matter on one hand, and in the truss-type systems in engineering on the other. The paper evolves by first giving a rather detailed presentation of one-dimensional and planar lattice models for classical continua. T...... hiện toàn bộ
Fast multipole accelerated boundary integral equation methods
Applied Mechanics Reviews - Tập 55 Số 4 - Trang 299-324 - 2002
Naoshi Nishimura
Fundamentals of Fast Multipole Method (FMM) and FMM accelerated Boundary Integral Equation Method (BIEM) are presented. Developments of FMM accelerated BIEM in the Laplace and Helmholtz equations, wave equation, and heat equation are reviewed. Applications of these methods in computational mechanics are surveyed. This review article contains 173 references.
Regularization Techniques Applied to Boundary Element Methods
Applied Mechanics Reviews - Tập 47 Số 10 - Trang 457-499 - 1994
Masataka Tanaka, V. Sládek, J. Sládek
This review article deals with the regularization of the boundary element formulations for solution of boundary value problems of continuum mechanics. These formulations may be singular owing to the use of two-point singular fundamental solutions. When the physical interpretation is irrelevant for this topic of computational mechanics, we consider various mechanical problems simultaneously...... hiện toàn bộ
A Review of Elastic–Plastic Contact Mechanics
Applied Mechanics Reviews - Tập 69 Số 6 - 2017
Hamid Ghaednia, Xianzhang Wang, Swarna Saha, Yang Xu, Aman Sharma, Robert L. Jackson
In typical metallic contacts, stresses are very high and result in yielding of the material. Therefore, the study of contacts which include simultaneous elastic and plastic deformation is of critical importance. This work reviews the current state-of-the-art in the modeling of single asperity elastic–plastic contact and, in some instances, makes comparisons to original findings of the auth...... hiện toàn bộ
Mechanics of carbon nanotubes
Applied Mechanics Reviews - Tập 55 Số 6 - Trang 495-533 - 2002
Dong Qian, and Gregory J Wagner, Wing Kam Liu, Min-Feng Yu, Rodney S. Ruoff
Soon after the discovery of carbon nanotubes, it was realized that the theoretically predicted mechanical properties of these interesting structures–including high strength, high stiffness, low density and structural perfection–could make them ideal for a wealth of technological applications. The experimental verification, and in some cases refutation, of these predictions, along with a nu...... hiện toàn bộ
