Discrete embedded modes in the continuum in 2D lattices
(Elsevier, 2020)
We study the problem of constructing bulk and surface embedded modes (EMs) inside the quasi-continuum band of a square lattice, using a potential engineering approach a la Wigner and von Neumann. Building on previous results ...
Embedded crack elements with non-uniform discontinuity modes
(Springer, 2006-01-01)
The consequences of the use of embedded crack finite elements with uniform discontinuity modes (opening and sliding) to simulate crack propagation in concrete are investigated. It is shown the circumstances in which the ...

A general technique to embed non-uniform discontinuities into standard solid finite elements
(2006-04-01)
A general technique to embed non-uniform displacement discontinuities into standard solid finite elements is presented. The technique is based on the decomposition of the kinematic fields into a component related to the ...

A Study on the Relationship of Embedded Sensitivity With Measuring Grid and Mode Shapes
(ASME-AMER SOC MECHANICAL ENG, 2011)
Embedded sensitivity analysis has proven to be a useful tool in finding optimum positions of structure reinforcements. However, it was not clear how sensitivities obtained from the embedded sensitivity method were related ...
Defect Modes, Fano Resonances and Embedded States in Magnetic Metamaterials
(Springer-Verlag Berlin Heidelberg, 2013)
We consider a simplified model of a nonlinear magnetic metamaterial,
consisting of a weakly-coupled, periodic split-ring resonator (SRR) array capable
of nonlinear capacitive response. We analyze three related problems: ...
Finite elements with embedded multiple cracks and non-uniform discontinuity modes
(2005-01-01)
Recently, several formulations of finite elements embedded with displacement discontinuity have been proposed to describe crack propagation independent of the element boundaries. By construction, these approaches are limited ...
