دانلود کتاب Analysis of aircraft structures : an introduction

As with the first edition, this textbook provides a clear introduction to the fundamental theory of structural analysis as applied to vehicles, aircraft, spacecraft, automobiles, and ships. The emphasis is on the application of fundamental concepts of structural analysis in everyday engineering practice. No assumptions are made with regard to the method of analysis. All approximations are accompanied by a full explanation of their validity. Repetition is an important learning tool, and so some redundancy appears to dispel misunderstanding. The number of topics covered in detail is limited to those essential for modern structural engineering practice. In this new edition, more topics, figures, examples, and exercises have been added. A primary change has been a greater emphasis on the finite element methods of analysis. Three new chapters are now included, and clarity remains the hallmark of this text Stress in structures -- Stresses and coordinate axis rotations -- Displacements and strains -- Strains in rotated coordinate systems -- The mechanical behavior of engineering materials -- Linearly elastic materials -- The theory of elasticity -- Plane stress theory of elasticity solutions -- Bending and extensional stresses in beams -- Beam bending and extensional deflections -- Additional beam bending topics -- Uniform torsion of beams -- Beam torsion approximate solutions -- Beam shearing stresses due to shearing forces -- Work and potential energy principles -- Precursor numerical analyses -- Introduction to the finite element method -- Finite element truss problems -- Basic aspects of multidimensional finite elements -- The unit load method for determinate structures -- The unit load method for indeterminate structures -- Thin plate theory -- Elastic and aeroelastic instabilities
