According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Out of the Crisis

Self-healing polymeric materials: A review of recent developments

Nonlinear Programming: A Unified Approach

This paper is a review of low-velocity impact responses of composite materials. First the term ‘low-velocity impact’ is defined and major impact-induced damage modes are described from onset of damage through to final failure. Then, the effects of the composite's constituents on impact properties are discussed and post-impact performance is assessed in terms of residual strength.

Review of low-velocity impact properties of composite materials

Topology optimization is the process of determining the optimal layout of material and connectivity inside a design domain. This paper surveys topology optimization of continuum structures from the year 2000 to 2012. It focuses on new developments, improvements, and applications of finite element-based topology optimization, which include a maturation of classical methods, a broadening in the scope of the field, and the introduction of new methods for multiphysics problems. Four different types of topology optimization are reviewed: (1) density-based methods, which include the popular Solid Isotropic Material with Penalization (SIMP) technique, (2) hard-kill methods, including Evolutionary Structural Optimization (ESO), (3) boundary variation methods (level set and phase field), and (4) a new biologically inspired method based on cellular division rules. We hope that this survey will provide an update of the recent advances and novel applications of popular methods, provide exposure to lesser known, yet promising, techniques, and serve as a resource for those new to the field. The presentation of each method's focuses on new developments and novel applications.

A survey of structural and multidisciplinary continuum topology optimization: post 2000

This chapter presents simple computational tools for determining the stress intensity factors associated with small sub-mm cracks in realistic complex geometries under arbitrary flight loads. Attention is also focused on small initial cracks that first grow as a complex three-dimensional (3D) shape and then transition into a through-the-thickness flaws with an oblique (part) elliptical crack front. Unless otherwise stated these tools are used to perform the lifting and crack growth analyses performed in the various chapters in this book.

Practical Computational Fracture Mechanics for Aircraft Structural Integrity

This paper discusses repairs and modifications to thin load bearing aircraft structures using Supersonic Particle Deposition technology, a topic which is currently under consideration by both the Australian Naval Aircraft Systems Project Office (NASPO) and the RAAF Directorate General Technical Airworthiness (DGTA). Ensuring continued airworthiness is of paramount importance and it is essential that (aircraft) structural integrity be maintained after repairs have been installed. To this end the present paper summarises the results of a series of experimental studies into the ability of SPD doublers to extend the fatigue life of thin aluminium structural components and the limit of viability (LOV) of fuselage lap joints.

SPD repairs to thin aluminium structures

On the analysis of composite structures with material and geometric non-linearities

This paper investigates the combined effect of corrosion and fatigue on the growth of cracks that arise from natural corrosion in steel bridges. It is shown that if these two effects need to be simultaneously analyzed. If not, then the resulting life is not conservative. Consequently, to enable a better understanding of the remaining life of structures this paper presents a simple methodology for performing this coupled analysis. The implication of this study to additively manufactured Ti-6Al-4V is also discussed.

Effect of corrosion and fatigue on the remaining life of structures and its implication to additive manufacturing

This paper discusses the stress analysis of adhesively bonded joints and therefore, by analogy, bonded repairs. Attention is focused on the effects of the rate dependence of structural adhesives and it is shown that the use of rate independent solutions to obtain the adhesive shear stresses and shear strains, cannot be said to be generally conservative
