Beginning with an introduction to the basic concepts of stresses in simple and composite elements, strains, and deformation of solids, the book moves through discussions on loads and stresses on the beam, which is a common structural element, torsion, and beam deflection. It then discusses columns and analysis of stresses in two dimensions. the boko also deals with strain energy concepts and their applications. The book provides an exhaustive coverage of important topics such as temperature stresses. elastic constants, bending moments, shear forces, theory of simple bending, analysis and design of shafts, stepped, indeterminate and compound shafts, close- and open-coiled helical springs, Euler equations and Rankine formula for columns, and Mohr's circle. TO reinforce the theoretical concepts, the text is supplemented by a large number of worked-out examples with step-by-step solution procedures as well as a large number of review questions and exercise problems. The text is also well supported by a large number of detailed illustrations.

Many books have been written about the finite element method; little however has been written about procedures that assist a practicing engineer in undertaking an analysis in such a way that errors and uncertainties can be controlled. In A Practical Guide to Reliable Finite Element Modelling, Morris addresses this important area. His book begins by introducing the reader to finite element analysis (FEA), covering the fundamental principles of the method, whilst also outlining the potential problems involved. He then establishes consistent methods for carrying out analyses and obtaining accurate and reliable results, concluding with a new method for undertaking error control led analyses which is illustrated by means of two case studies. The book addresses a number of topics that: Systematically cover an introduction to FEA, how computers build linear-static and linear-dynamic finite element models, the identification of error sources, error control methods and error-controlled analyses. + Enable the reader to support the design of complex structures with reliable, repeatable analyses using the finite element method. + Provide a basis for establishing good practice that could underpin a legal defence in the event of a claim for negligence. A Practical Guide to Reliable Finite Element Modelling will appeal to practising engineers engaged in conducting regular finite element analyses, particularly those new to the field. It will also be a resource for postgraduate students and researchers addressing problems associated with errors in the finite element method.

Purpose and Background: Soil dynamics is the branch of soil mechanics which deals with the behavior of soil and foundations under dynamic loads. Operation of rotary machines or hammers, and earthquake ground motions constitute a class of dynamic loads that usually challenge engineers in their design of different kinds of foundations. The main goal of this seminar is to provide a better understanding to practicing engineers and architects of the design and evaluation of foundations under this class of dynamic loads. Topics to be discussed include: Basic Principles of Soil Dynamics: Fundamental distinctions between static and dynamic problems; basic notions of soil dynamics; the nature of different types of dynamic loads; the significance of soil-structure interaction; dynamic soil properties. Dynamic Properties of Shallow and Pile Foundations: Impedance functions of foundations and pile groups; definition of stiffness, and damping, for circular shallow foundations and piles; non-circular shallow foundations; mathematical models for pile analysis. Rotating Machine and Hammer Foundations: Harmonic excitations due to rotary machines; response of rigid foundations in 1DOF; evaluation of the effects of vibration; coupled response of rigid foundations in two degrees of freedom; types of hammers and hammer foundations; design criteria; mathematical models; impact forces and impact eccentricity. Vibration Damage and Remedial Measures for Machine Foundations: Damage and disturbance; problem assessment and evaluation; remedial principles; examples from different industries; sources of error. Geotechnical Earthquake Engineering Fundamentals: Sources of seismic hazard; introduction to seismic waves; ground motion characterization and response spectra; evaluation of soil dynamic properties; site response analysis. Design of Foundations for Seismic Loads: Dynamic bearing capacity of shallow foundations; dynamic response analysis of shallow foundations; conventional methods of analysis of piles under seismic loads; seismic analysis of deep caissons; seismic design of retaining walls; solved examples from industry. Computer applications using DYNA-5: Types of foundations; types of soil models; types of loads; types of analysis and output; practical applications using DYNA-5.
