Crack-path field and strain-injection techniques in computational modeling of propagating material failure
(Elsevier, 2014-01)
The work presents two new numerical techniques devised for modeling propagating material failure, i.e. cracks in fracture mechanics or slip-lines in soil mechanics. The first one is termed crack-path-field technique and ...
Nonlinear Sliding of Discontinuous Vector Fields and Singular Perturbation
(2020-01-01)
We consider piecewise smooth vector fields (PSVF) defined in open sets M⊆ Rn with switching manifold being a smooth surface Σ. We assume that M\ Σ contains exactly two connected regions, namely Σ + and Σ -. Then, the PSVF ...
Analyzing dynamical gluon mass generation
(Sociedade Brasileira Fisica, 2007-03-01)
We study the necessary conditions for obtaining infrared finite solutions from the Schwinger-Dyson equation governing the dynamics of the gluon propagator. The equation in question is set up in the Feynman gauge of the ...

Silicon Field-Emission Devices Fabricated Using the Hydrogen Implantation-Porous Silicon (HI-PS) Micromachining Technique
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
This paper presents a relatively simple method to fabricate field-emitter arrays from silicon substrates. These devices are obtained from silicon micromachining by means of the HI-PS technique-a combination of hydrogen ion ...
Regularization and singular perturbation techniques for non-smooth systems

Conformal defects from string field theory
(2021-01-01)
Unlike conformal boundary conditions, conformal defects of Virasoro minimal models lack classification. Alternatively to the defect perturbation theory and the truncated conformal space approach, we employ open string field ...
Effective lagrangian for a mass dimension one fermionic field in curved spacetime
(2018-02-01)
In this work we use momentum-space techniques to evaluate the propagator G(x, x′) for a spin 1/2 mass dimension one spinor field on a curved Friedmann-Robertson-Walker spacetime. As a consequence, we built the one-loop ...
