Performance evaluation of patch repairs on historic concrete structures (PEPS): the evolution of conservation repairs on the Historic England Phase II test sites and PEPS Phase II results [PDF]

open access: yesMATEC Web of Conferences, 2022
Historically, little effort had been made to match patch repairs to culturally significant reinforced concrete structures so that they are effective and sustain the aesthetic values of the structure.

Evaluation of mechanical properties of friction stir welded commercially pure aluminium

open access: yesMATEC Web of Conferences, 2018
In this study, friction stir welding (FSW) of commercially pure aluminium is carried out. The main defects existing in this process are cavity, irregular material flow due to unsuitable selection of welding parameters.

Selection of cutting parameters for the machinability of Inconel 718 using Grey Relational Analysis

open access: yesMATEC Web of Conferences, 2018
Inconel 718 is considered to be most difficult to machine superalloy because of its high shear strength, work hardening and precipitation hardening. Abrasive particles which are in microstructure have tendency have forming chip to be welded to tool and ...

Non destructive testing (NDT) with high Tc RF SQUIDs

open access: yesJournal of Physics: Conference Series, 2008
A high Tc rf SQUID nondestructive evaluation (NDE) set-up has been realized to measure the eddy current induced field in different aluminum samples, under a weak AC and low frequency magnetic excitation. An efficient and simple analytic modeling method has been also developed for computing the magnetic field created by the induced eddy current in the ...
