US Army Welding Operations and Finite Elements for Non_Linear Continua Structures




US Army Welding Operations Parts I & II

The purpose of this course is to introduce the basic requirements involved in metal-arc welding operations. The scope of this subcourse consists of describing the classification of electrodes and their intended uses; describing automotive welding processes, materials and identification processes; describing the methods of destructive and nondestructive testing of welds and troubleshooting procedures; describing the type and techniques of joint design; and describing the theory, principles, and procedures of welding armor plate. Welding is one of the most important functions performed in both an intermediate direct support (IDS) and intermediate general support (IGS) maintenance company.

Finite Elements for Non_Linear Continua Structures

Nonlinear finite element analysis is an essential component of computer aided design. The purpose of this book is to describe the methods of nonlinear finite element analysis for solid mechanics. Our intent is to provide an integrated treatment so that the reader can gain an understanding of the fundamental methods, a feeling for the comparative usefulness of different approaches and an appreciation of the difficulties which lurk in the nonlinear world. For both users and developers of nonlinear finite element programs, an understanding of the fundamental concepts of nonlinear finite element analysis is essential. Without an understanding of the fundamentals, a user must treat the finite element program as a black box that provides simulations. Like many finite element books, this book presents a large variety of methods and recipes for the solution of engineering and scientific problems by the finite element method. It is the objective of this book to provide this understanding and to make the reader aware of the many interesting challenges and opportunities in nonlinear finite element analysis. One of the themes of this book is partially the different descriptions that are used in the formulation of the governing equations and the discretization of the continuum mechanics.
