Non Linear Modelling of Masonry Structures Under Cyclic Loads

2008
A continuum damage model for historical masonry, able to describe its non-linear behaviour under both static and dynamic cyclic loads, is presented. The model is based on a micromechanical approach. The hypothesis of plane stress is considered. The finite element method is adopted as a framework for numerical implementation.

Short term load forecasting using non-linear template matching

IEEE Africon '11, 2011
Accurate short term load forecasting plays a very important role in power system management. As electrical load data is highly non-linear in nature, in the proposed approach, we first use a Reproducing Kernel Hilbert Space (RKHS) method to fit the data.

Non-linear analysis of vertically loaded piled rafts

Computers and Geotechnics, 2015
Abstract While the availability of 3D FEM or FDM analyses has greatly contributed to the increasing use of piled rafts for high rise structures, there is a need in industry for practical analysis methods which would also allow the adoption of piled rafts for more ordinary structures.

Load Incrementation in a Non-linear Analysis

2014
A structure can be loaded by a number of loads of different type. We restrict ourselves to force-type loads such as forces, moments and distributed loads like line and surface loads, e.g. pressure. The reference loads contained in the vector f 0 ext can be increased proportionally.

Failure analysis of container stacks by non-linear FE simulations under non-linear inertial loads

2015
In this paper a specific procedure for the structural assessment of a container stack is implemented to a realistic case in order to evaluate its effectiveness in the prediction of the operational limits of a container vessel. The feasibility of an extensive calculation based on such procedure is tested, paving the way to the direct analysis of a ...

Non-linear 3D piping analysis under stochastic dynamic loads

Nuclear Engineering and Design, 1991
Abstract A new analytical method is presented for non-linear 3D piping systems subjected to stochastic dynamic loadings. First, the paper describes the development of an empirical formulation for the strength and deformation characteristics of piping systems based on a detailed finite-element shell analysis of various pipebends.

Autonomous Induction Generator Feeding Non-linear and Unbalanced Loads

2018 IEEE Biennial Congress of Argentina (ARGENCON), 2018
Is propose an excitation system for autonomous induction generators that feeds non-linear and unbalanced loads. The generator is composed of an induction machine (IM) of the squirrel cage type, the excitation system has a capacitor bank and a four-wire converter connected in parallel with the IM.

Buckling load of non-linear systems with multiple eigenvalues

International Journal of Solids and Structures, 1974
Abstract For structural systems with a coincident lowest eigenvalue λ c , the influence of imperfections on the buckling of the systems depends to a very large extent upon the distribution of the imperfections. Moreover, the system may buckle either at a limit point or at a bifurcation point before this limit point is reached.

Random Loads Fatigue: The Simulation of Non-Linear Systems

Volume 1: 22nd Biennial Conference on Mechanical Vibration and Noise, Parts A and B, 2009
In this paper the problem of the correct evaluation of the stress state of mechanical components of non linear systems in the frequency domain was analysed. This is one of the most important steps in the frequency domain evaluation of the fatigue behaviour of components under random loads.

Design of stand-by generators for non-linear loads

Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 2003
The author discusses the causes of the problems and the design changes possible in the generator to minimize the voltage waveform distortion. A method for calculating the additional losses in the generator due to harmonic currents is presented. The discussion refers specifically to generators of the salient pole type in the 10-2000 kW range, but the ...
