Crack deflection processes—I. Theory

Acta Metallurgica, 1983
A fracture mechanics approach has been used to predict fracture toughness increases due to crack deflection around second phase particles. The analysis is based on a determination of the initial tilt and the maximum twist of the crack front between particles, which provides the basis for evaluating the deflection-induced reduction in crack driving ...

Electron Beam Deflection: Part I. Small-Angle Deflection Theory

Journal of Applied Physics, 1947
Two general mathematical methods are discussed which may be used to study the effects of electric and/or magnetic deflection fields on electron beams. The basic equations for the ``path method'' are the equations of motion of Newton or Euler-Lagrange.

Arc perturbation theory of magnetic deflection

Journal of the Society for Information Display, 2001
Abstract—A perturbation theory is presented for deflection angles larger than 45°. Several parameters that previously had to be treated perturbatively are handled exactly. The theory can be used for a systematic study of front‐of‐screen errors in slim CRTs.

Modeling and PDE Theory for The Large Deflections

2022
Flutter is defined as a self-excitation of a thin structure where a surrounding flow destabilizes its natural elastic modes. Cantilevers are particularly prone to flutter, and it has been shown that this instability can induce large displacements from which mechanical energy can be captured via piezoelectric laminates.

Solving Boundary Value Problems in Plate Deflection Theory

SIMULATION, 1981
Analysing the deflection of plates or beams generally requires the solution of a two-point boundary value probzem associated with an ordinary differential equation. Such problems can be solved by finite difference methods, by shooting techniques, or by spline approximation. We develop and analyse these three types of methods.

Theory of Unsymmetric Magnetic-Deflection Coils

IEEE Transactions on Consumer Electronics, 1984
We have developed a formalism for calculating the deflection errors due to a slightly unsymmetric magnetic deflection coil. Explicit expressions for the errors have been derived using an aberration theory type approach, but including the even-order contributions and retaining terms up to fourth order.

A Generalized Deflection Theory for Suspension Bridges

Transactions of the American Society of Civil Engineers, 1935
AN IMPROVED AND EXTENDED DEFLECTION THEORY FOR SUSPENSION BRIDGES IS PRESENTED IN THIS PAPER. THE THEORY IS GENERALIZED TO INCLUDE STRUCTURES OF ANY NUMBER OF SPANS, CONTINUOUS OR NON-CONTINUOUS, SYMMETRICAL OR UNSYMMETRICAL, AND WITH OR WITHOUT TIE CABLES.

Corrected Deflection Theory of Suspension Bridges

Transactions of the American Society of Civil Engineers, 1960
Theory presented considers several effects neglected in previous theories such as those due to shear force and to elongation of cable; only theory, and not practical method of solution, is dealt with.

Engineering Large Deflection Theory for Thick Plates

Journal of Engineering Mechanics, 1989
A refined theory for the bending of plates with moderately large deflections is proposed. The presented theory is an extension of the technical theory of plates for small strains. The plate theory presented by Voyiadjis and Baluch incorporates rotatory inertia.

COMPARISON OF THEORY AND EXPERIMENT ON AEROACOUSTIC LOADS AND DEFLECTIONS

Journal of Fluids and Structures, 1999
Abstract The correlation of acoustic pressure loads induced by a turbulent wake on a nearby structural panel is considered: this problem is relevant to the acoustic fatigue of aircraft, rocket and satellite structures. Both the correlation of acoustic pressure loads and the panel deflections, were measured in an 8-m diameter transonic wind tunnel ...
