Friction stir welding of commercially available superplastic aluminium [PDF]
, 2010 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A series of Friction Stir Welds (FSW) has been produced in order to optimise tool designs and weld/process variables to minimise flaws in the weld and ...

Rolling to control residual stress and distortion in friction stir welds [PDF]
, 2010 Considerable residual stress and distortion can be produced by friction stir welding, impeding industrial implementation. Finite element analysis has been used to develop three innovative rolling methods that reduce residual stress and distortion in ...

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Abnormal fracture of 7085 high strength aluminum alloy thick plate joint via friction stir welding
Journal of Materials Research and Technology, 2019 7xxx series high-strength aluminum alloy joints by friction stir welding (FSW) generally fracture in the heat affected zone (HAZ), i.e. the lowest hardness zone (LHZ) during tensile test. However, the experiment results of this study indicate that defect-

Thermodynamics and kinetics of boundary friction [PDF]
, 2011 A deterministic theory describing the behavior of an ultrathin lubricant film between two atomically-smooth solid surfaces is proposed. For the description of lubricant state the parameter of excess volume arising due to chaotization of solid medium ...

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Advanced Engineering Materials, EarlyView.Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Structural response of A286 superalloy to rotary friction welding at different rotation speed
Materials Research Express, 2020 Rotary friction welding was conducted on A286 with a diameter of ϕ 25 mm under 300, 900 and 2100 rpm to understand the structural response of the joint welded at different rotation speeds.

CoRR, 2022 I present a method for text analysis based on an analogy with the dynamic friction of sliding surfaces. One surface is an array of points with a 'friction coefficient' derived from the distribution frequency of a text's alphabetic characters. The other surface is a test patch having points with this friction coefficient equal to a median value ...
