Effect of external load on angular distortion in fillet welding

Materials & Design, 2012
Abstract This paper studied the effects of the magnitude, the direction, and the release time of pre-tensioning stress on welding distortion and residual stress on thin steels for a ship in the pre-tensioning method above using the finite element method.

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.

Limiting Tolerable Settlement and Angular Distortion for Building Foundations

Probabilistic Applications in Geotechnical Engineering, 2007
To develop reliability-based serviceability criteria for foundation design, the probability distributions of limiting tolerable displacements should be available. In this study, displacement information of 380 buildings, including 124 cases from Hong Kong and Mainland China, is collected for analysis.

ANGULAR DISTORTION IN BUTT ARC WELDING

2018
The importance of fusion weldingtechnology has been widely recognized in the manufacturing process of varioussteel structures such as ships, bridges, construction machines, power plants,and automobiles. However, a significant disadvantage of fusion welding is thatit often generates unacceptable levels of geometric imperfections such asshrinkage and ...

Angular Distortion Removal of THz Anisotropic Dichroism Microscope

2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2019
We have developed a stationary sample THz anisotropic dichroism microscope as a powerful tool for material characterization. The key innovation is the use of an iso-response curve defined by the terahertz and detection light polarizations. Here we show that following a continuous iso-response curve introduces angular distortion in the spectrum, and ...

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.

Urbach edges and angular distortions in a-Si:H and related alloys

Journal of Non-Crystalline Solids, 1989
Abstract We propose a general discussion of the experimental correlation between the valence band tail slope parameter k B T v and the rms deviation ΔΘ b of the SiSi bond angle distribution which has been observed by various authors in doped and undoped a-Si:H, as well as in a-SiGe:H and a-SiN:H alloys.
