Numerical Integrators for Elastic-Secondary Creep

Journal of Engineering Mechanics, 1997
A method has been developed for building error maps to present the accuracy of time-dependent inelastic material models similar to the error maps used for time-independent plasticity. The elastic-secondary creep constitutive model with a Norton creep behavior is used throughout the paper to illustrate the method.

Singular integral equations in elastic dielectrics

International Journal of Solids and Structures, 1975
Abstract Galerkin representations for the displacement vector, polarization vector and the potential field are obtained by elementary matrix inversions of the equations of equilibrium. Matrices of fundamental solutions of an infinite elastic dielectric continuum subjected to a concentrated body force, an electric force, and a charge density, are ...

Eshelby integral formulas in gradient elasticity

Mechanics of Solids, 2010
Eshelby integral formulas play a fundamental role in mechanics of composite materials, because they provide an efficient tool for determining the average properties of dispersion-filled materials. For example, their use in the framework of the self-consistent averaging method actually gives a final and quite precise solution to the problem of ...

Laser Testing of Integrated Circuits (ELASTIC®)

SPIE Proceedings, 1990
The inadequacy of the stuck-at fault model has been well aired and documented.1 ,2 All studies agree that this model does not reflect the physical failures of real devices,3 principally because such failures do not exhibit a 1:1 mapping onto the logic domain.2 ,4 Circuit layouts which are based on stick diagrams do however reflect the physical domain ...

Grid-based volume integration for elasticity: Traction boundary integral equation

Engineering Fracture Mechanics, 2017
Abstract A volume integral algorithm for the non-homogeneous 3 D elasticity traction boundary integral equation is presented. The body force volume integral is exactly split into a relatively simple boundary integral, together with a remainder volume integral that can be evaluated using a regular grid of cuboid cells covering the problem ...

Integral representations in plane anisotropic elasticity

AIP Conference Proceedings, 2013
The representation of general solutions of Lame system of plane elasticity is given with the help of so-called Douglis analytic functions. Using this representation generalized potentials of double layer are introduced and the basic boundary value problems for Lame system are reduced to equivalent Fredholm integral equations on the boundary.

Contoured Elastic-Membrane Microvalves for Microfluidic Network Integration

Journal of Biomechanical Engineering, 1999
A contoured elastic-membrane microvalve is presented that enables integrated microfluidic processing at the network level. This method takes advantage of two ideas to improve performance: flexible elastic membranes (which enable high-performance shutoff and reduced footprint), and three-dimensionally contoured valve geometries (which reduce dead volume,

Boundary integral equations of unique solutions in elasticity

Applied Mathematics and Mechanics, 1999
Boundary integral equations for elastostatic problems do not have a unique solution. This deficiency is eliminated here by adding supplementary conditions formulated as integrals over the boundary. The approach is briefly illustrated by a simple example.

Numerical integration of non‐linear elastic multi‐body systems

International Journal for Numerical Methods in Engineering, 1995
AbstractThis paper is concerned with the modelling of nonlinear elastic multi‐body systems discretized using the finite element method. The formulation uses Cartesian co‐ordinates to represent the position of each elastic body with respect to a single inertial frame.

Elastic Integration in Civic Do-ocracies

2020
Civic engagement in welfare issues is increasingly partaken in informal, non-membership based formats. The paper explores this tendency through the study of collective civic action performed in ‘do-ocracies’, which are networks based on principles of decentralization and action.
