Nonlinear Maxwell modelling of inverse relaxation in yarns and fabrics

An attempt has been made to fit the derived equation on the experimental inverse relaxation curves by employing Levenberg-Marquardt’s method for nonlinear regression and calculation of the constant values involved in the equation. The relaxation curves can be classified into ordinary relaxation, mixed relaxation and inverse relaxation curves. There seems to be good concurrence between the experimental and the fitted inverse relaxation curves

Study of Hydrogen Permeation Behaviour of High Strength Aluminium Alloys

Aluminum, with its multifaceted wonders has amazed and attracted peoples to use i t in variety of applications. Aluminium offers a wide range of properties that can be engineered to the demands of specific applicaions through the choice of alloy, temper and fabrication process

Localised corrosion of 2124SiCp composite

Influence of alternate immersion in Sodium chloride solution, exposure to salt spray, EXCO test (ASTM-G34), Electrochemical test and marine exposure on 2124 aluminium alloy composite plates reinforced with 10 vol.% SiC particulate and the 2124 base alloy, were studied, and also the localised corrosion like pitting and exfoliation behaviours were reported in this paper

The amplitude and wavelength of the hairiness periodicities would be useful for analyzing the causes of hairiness formation from the point of view of producing quality yarns.</span
