Abstract

This book is exclusievely designed for the beginners who would deal with finite element method (FEM). The book has been written in simple, lucid and easily understandalde fashion. The author has used his long teaching experience of the subject and derived FEM formulation in his own way, in a slightly different approach from the available books on FEM. There are fourteen well-organised chapters, and four appendices on Matrix algebra, Solution of equation, Numerical integration and Rayleigh-Ritz method. The appendices are quite useful for learners. However, the book has few limitations. The author has not discussed FEM formulation for Fluid Mechanics and Heat Transfer problems. This is understandably due to the fact that the focus of the book is mainly stress analysis of different types of structural problems. Functional and Galerkin's apprach have also not been discussed in the book. Despite this, the book will be very essential for learners, and can be highly recommended to the students who take FEM as subject in undergraduate and post graduation level. Another feature of this publication is web-basd availability of demo programme and help file which would benefit learners.

Abstract

Every metal cutting process is associated with the combination of indentation processes. Thus, studying indentation has a great importance in mechanics of metal cutting process. The present work deals with the indentation of a conical diamond point indenter to a semiinfinite block of mild steel. In indentation process, some portion of the block is plastically deformed. The present work investigates zone of extensions of plastic zone for different types of indenters having varying cone angles through finite element analysis and compare the results with Slip-line field approaches. The present work considers semi-apex angle of the cone to be greater than 45°.
