This book presents fused deposition modeling (FDM) which is an additive manufacturing (AM) process to fabricate 3D parts from a build-up of 2D layers. The chapters present an experimental analysis of fatigue characteristics of FDM-processed PLA samples. The results indicate that the concentric build orientation provides highest cycles of fatigue, ultimate strength, and impact energy. The effect of layer orientation on the fatigue behavior of 3D-printed PLA samples is investigated in this case study.

This book introduces basic concepts related to computer-aided simulation of welding and prepares the reader to perform the simulation of welding by commercial simulation software.

This book helps the reader to implement these concepts in any commercial software to simulate the welding process according to their own requirement.

This book presents, in a self-contained fashion, a series of studies on flow and heat transfer in porous media, in which distinct energy balances are considered for the porous matrix and for the permeating fluid. Detailed mathematical modeling is presented considering both volume and time averaging operators simultaneously applied to the governing equations. System involving combustion in the gaseous phase, moving bed and double-diffusion mechanism are analyzed. Numerical results are presented for each case. In the end, this book contains the description of a tool that might benefit engineers in developing and designing more efficient thermal equipment.

This book provides a state-of-the-art review of the fail-safe and damage tolerance approaches, allowing weight savings and increasing aircraft reliability and structural integrity. The application of the damage tolerance approach requires extensive know-how of the fatigue and fracture properties, corrosion strength, potential failure modes and non-destructive inspection techniques, particularly minimum detectable defect and inspection intervals. In parallel, engineering practice involving damage tolerance requires numerical techniques for stress analysis of cracked structures. These evolved from basic mode I evaluations using rough finite element approaches, to current 3D modeling based on energetic approaches as the VCCT, X-FEM or meshless techniques.This book provides a concise introduction to this subject.
