Creep-fatigue analysis by Strainrange Partitioning

Strainrange Partitioning provides unifying framework for characterizing high-temperature, low-cycle, creep-fatigue properties of metals and alloys. Method offers distinct advantage to designers of immediately providing reliable upper and lower bounds on cyclic life for any type of inelastic strain cycle that may be encountered in service

Executive remuneration consultancy in the UK: exploring a professional project through the lens of institutional work

This article responds to recent calls to examine the development of professionalism through the lens of institutional theory. We investigate the development of the new professional service of executive remuneration consultancy (ERC) in the UK through the lens of institutional work. Specifically, drawing upon Lawrence and Suddaby (2006) and Suddaby and Viale (2011), we explore the relationship between macro-scale occupational/organizational and micro-scale individual-level dynamics of the ERC professional project and situate its development in relation to the broader field of executive remuneration practices. We show that the institutional work of creating the new professional project is contested and that the ERC development may be better understood as part of broader efforts to create and maintain the institution of executive pay-setting practices. We argue that the institutional work lens has the potential to produce a more nuanced understanding of the internal dynamics of the ERC professionalization process and its role in reconfiguring broader institutional arrangements. By exploring the analytical purchase of the concept of institutional work, the article contributes to the emerging body of empirical evidence outlining the potential of (neo-) institutional approaches to offer a more productive understanding of contemporary professionalis

Hydrodynamic modelling of accretion flows

In the proceedings of this, and of several recent close binary conferences, there have been several contributions describing smoothed particle hydrodynamics simulations of accretion disks. It is apposite therefore to review the numerical scheme itself with emphasis on its advantages for disk modelling, and the methods used for modelling viscous processes.Comment: 3 pages, to appear in proceedings of IAU Colloquium 194: Compact binaries in the galaxy and beyon

Determination of stresses in gas-turbine disks subjected to plastic flow and creep

A finite-difference method previously presented for computing elastic stresses in rotating disks is extended to include the computation of the disk stresses when plastic flow and creep are considered. A finite-difference method is employed to eliminate numerical integration and to permit nontechnical personnel to make the calculations with a minimum of engineering supervision. Illustrative examples are included to facilitate explanation of the procedure by carrying out the computations on a typical gas-turbine disk through a complete running cycle. The results of the numerical examples presented indicate that plastic flow markedly alters the elastic-stress distribution
