Dynamics of a deflectable-nose missile

Science China Technological Sciences, 2012
The dynamics of a supersonic missile with a deflectable nose are studied. To describe the effects of nose deflection on the dynamic model, theorems of momentum and angular momentum are adopted to develop the translational equation and rotation equation, respectively. Because the exact model is complex, it is simplified.

Dislocations Deflect and Perturb Dynamically Propagating Cracks

Physical Review Letters, 2004
We demonstrate that in single-crystal silicon short-range collisions of a dynamically propagating crack with stationary, intrinsic, "inclined" dislocations generate local crack deflections that grow to a large surface perturbation. Experiments show that when the crack collides with a single dislocation, the perturbation height is about 8 nm, but when ...

Dynamic Deflection of Paper Emerging from a Channel

Journal of Vibration and Acoustics, 1991
In many machines handling lightweight, flexible sheets, the sheet must transit an open space. Examples include magnetic tape drives, xerographic copiers, and sewing machines. The nonlinear theory of the elastica has often been used to model nonlinear, static deflections. Dynamic modeling is more difficult, and far less studied.

COMPLEX DYNAMICAL BEHAVIORS OF DEFLECTION ROUTING ON GRID NETWORKS

International Journal of Bifurcation and Chaos, 2012
Deflection routing is a mechanism to route packets away from congestion. Traditional shortest path routing uses only the static topological information as input, whereas deflection routing takes into account the dynamic queue length information. In the simplest form of deflection routing, a packet being dropped due to queue buffer overflow is "rescued"

Interpretation of Dynamic Pavement Deflections

1980
In 1977, a methodology was .developed to evaluate pavement performance using dynamic (Road Rater) deflections. Since then, additional research has resulted in modifications ill the procedures. This paper presents the procedures presently used to evaluate flexible pavement structures.

Dynamic deflection analysis of a planar robot

Computers & Structures, 1994
Summary: This study considers the robot mechanism (linkage) as an elastic body. A finite element method is utilized to discretize and simplify the robot from a numerous degrees of freedom system into a structure with finite beam elements. Here the beam element refers to the Timoshenko beam element deduced by the Timoshenko beam theory.

Elasto‐Dynamic Analysis of Pavement Deflections

Journal of Transportation Engineering, 1984
An elastodynamic analysis of pavement response to harmonic‐load nondestructive testing is presented. The method is based on a discrete layer approach that assumes linear variation of displacements in the direction of layering between adjacent interfaces of thin artificial pavement sublayers. The method is applied to typical four‐layer flexible pavement

Dynamic Teaching on the Deflection Determining of Beams

Advanced Materials Research, 2014
The object of this study is applying the mathematical concepts to help students for learning the deflection analysis of beams. We integrate the concepts and techniques of calculus, derivative, programming writing, and deflection of beam device manufacture to achieve the purpose of this work. The results show the computer dynamic teaching and simulation

Finite deflection dynamics of elastic beams

International Journal of Solids and Structures, 1974
Abstract Solutions are obtained for the problem of an infinite elastic beam subjected to essentially constant velocity boundary conditions at one point of the beam. The effects of finite deflections, normal force, rotatory inertia and shear deformation are included.
