We study the reliability of phase oscillator networks in response to fluctuating inputs. Reliability means that an input elicits essentially identical responses upon repeated presentations, regardless of the network’s initial condition. Single oscillators are well known to be reliable. We show in this paper that unreliable behavior can occur in a network as small as a coupled oscillator pair in...

Based on an original interpolation method we develop a beam nite element formulation on the Lie group SEp3q which relies on a mathematically rigorous framework and provides compact notations. We work out the beam kinematics in the SE(3) context, the beam deformation measure and obtain the expression of the internal forces using the virtual work principle. The proposed formulation exhibits impor...

In the present work performance of finite element formulations with different reduced integration strategies is evaluated for Contact Mechanics applications. One-point quadrature and selective are utilized here using hourglass control to suppress volumetric shear locking materials incompressible plastic behavior bending-dominated problems. A corotational formulation adopted deal physically geom...

Abstract In this contribution, it is demonstrated that the mesh sensitivity of linear elastic Reissner–Mindlin finite‐element plate formulations can be significantly reduced by using a Petrov–Galerkin‐based approach. contrast to usual Bubnov–Galerkin method, Petrov–Galerkin methods are generally characterized fact test function and trial approximated different shape functions. To provide an ove...

We study the approximation of the Reissner-Mindlin plate using the p/hp version of the finite element method (FEM). Our goal is to identify a method that: (i) is free of shear locking, (ii) approximates the boundary layer independently of the thickness of the plate and (iii) converges exponentially with respect to the number of degrees of freedom. We will consider both standard and reduced cons...

An analysis is presented for a recently proposed nite element method for the Reissner{ Mindlin plate problem. The method is based on the standard variational principle, uses nonconforming linear elements to approximate the rotations and conforming linear elements to approximate the transverse displacements, and avoids the usual \locking problem" by interpolating the shear stress into a rotated ...

Paper focuses on biomechanics, specifically on locking cortical bone screws in angularly stable plates used for the treatment of bone fractures in the medical fields of traumatology and orthopaedics. During extraction of titanium-alloy implants, problems are encountered in an effort to loosen some locking bone screws from the locking holes of an angularly stable plate and the subsequent strippi...

Abstract This paper introduces a new concept called self-updated finite element (SUFE). The (FE) is activated through an iterative procedure to improve the solution accuracy without mesh refinement. A mode-based formulation devised for four-node and assumed modal strain employed bending modes. search optimal directions implemented deep learning given deformation minimize shear locking. proposed...

We report on stable dual-wavelength operation in passive and hybrid mode-locking of a 10GHz two-section InAs/InP(100) quantum dot laser diode operating at 1.5μm. The range of stable passive mode-locking, the locking range of hybrid mode-locking and detailed measurements of the phase modulation in the output pulses will be presented. Keywordsmode-locked laser diode; quantum dot; hybrid mode-lock...
