Alpha-gamma angular correlations and the distorted-waves theory

Physics Letters, 1962
The angular correlation between the alpha particle inelastically- scattered from the 4.43-Mev level of C/sup 12/ and its de-excitation gamma ray was measured at various scattering angles to test theoretical predictions of the correlation parameters. Data are presented in graphical form. (L.N.N.)

Fatigue Strength of Butt-Welded Joints with Angular Distortion

1981
The fatigue strength of butt-welded joints having angular distortion is investigated for the amount of angular distortion, overstressing prior to fatigue loading, and the distance between loading points. The cyclic strain range, measured near the toe of the reinforcement of weld, correlate with the fatigue life regardless of the amount of angular ...

Simple all-sky camera without angular distortion

Hvar Observatory bulletin, 1993
All-sky cameras with spherical mirrors are used in several astronomical applications. However, such a camera suffers from angular distortion near the edge of the image. By using an aspberical mirror of appropriate shape, it is posssible to eliminate angular distortion.

Analysis of angular distortion in weldments using laminated plate theory

Science and Technology of Welding and Joining, 2000
The problems of distortion and residual stresses in and around a welded joint are of major concern in heavy industry. In the present work, a formula for weld induced angular distortion, in terms of weld parameters such as heat input and plate thickness, is developed analytically using an infinite laminated plate theory to consider an elliptical ...

Modelling of angular distortion of double-pass butt-welded plate

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008
Adequate top and bottom side weld reinforcements are important for single-side submerged arc welded butt joints as the shrinkage forces generated due to the solidification of top side weld reinforcements and bottom side weld reinforcements can cancel out each other to minimize angular distortions.

Effects of mechanical constraints on angular distortion of welding joints

Science and Technology of Welding and Joining, 2002
During the manufacture of steel structures, welding deformations have undesirable effects on the accuracy of assembly, external appearance, buckling strength, fatigue strength, etc. In particular, in such large steel structures as ships, welding deformations produced during assembly lead to variations in dimensions which require considerable time and ...

Application of Computer Control in the Angular Distortion Measurement System

Applied Mechanics and Materials, 2013
A new real-time angular distortion measurement system, composed of devices i.e. the photoelectrical auto-collimating collimator and the reflex light-tube installed on deck, is developed in this paper. Real-time measurement of vessels bi-dimensional angular distortion is achieved by using this computer control system.

Numerical simulation of transient welding angular distortion with external restraints

Science and Technology of Welding and Joining, 2009
A multibody coupling finite element model, in which worktable, clamping strip, welding plate and fixture are included, is built to simulate the welding transient distortions under restraining forces. Overlaying welding experiments are also carried out to measure transient welding distortions and dynamic restraining forces to validate the model.
