Wear In Advanced Engineering Applications And Materials


Book Description

Wear is one of the main reasons mechanical components and materials become inoperable, rendering enormous costs to society over time. Estimating wear allows engineers to predict the useful life of modern mechanical elements, reduce the costs of inoperability, or obtain optimal designs (i.e. selecting proper materials, shapes, and surface finishing according to mechanical conditions and durability) to reduce the impact of wear.Wear in Advanced Engineering Applications and Materials presents recent computational and practical research studying damage and wear in advanced engineering applications and materials. As such, this book covers numerical formulations based on the finite element method (FEM) — and the boundary element method (BEM) — as well as theoretical and experimental research to predict the wear response or life-limiting failure of engineering applications.




Advanced Materials in Engineering Applications


Book Description

The formability features of sheets made of the alloy Al 8011 are examined experimentally and the results are compared with the numerical ones in this research. Through an axisymmetric finite element simulation of the Erichsen cupping test, formability characteristics were evaluated. The Erichsen cupping test was used to exam□ine the effects of several factors, including friction at the punch-sheet contact and sheet thickness. The nonlinear finite element method is used to calculate the dome height, stress, and strain values for the aluminum sheet, and the results are then compared to the numerical ones. The findings demonstrated that the Al 8011 alloy’s form□ability greatly rises with increasing sheet thickness. The formability is significantly impacted by the lubricant. The application of the finite element technique to forecast the formability of Al 8011 alloy.




Biomimetic Principles and Design of Advanced Engineering Materials


Book Description

This book explores the structure-property-process relationship of biomaterials from engineering and biomedical perspectives, and the potential of bio-inspired materials and their applications. A large variety of natural materials with outstanding physical and mechanical properties have appeared in the course of evolution. From a bio-inspired viewpoint, materials design requires a novel and highly cross disciplinary approach. Considerable benefits can be gained by providing an integrated approach using bio-inspiration with materials science and engineering. The book is divided into three parts; Part One focuses on mechanical aspects, dealing with conventional material properties: strength, toughness, hardness, wear resistance, impact resistance, self-healing, adhesion, and adaptation and morphing. Part Two focuses on functional materials with unique capabilities, such as self-cleaning, stimuli-response, structural color, anti-reflective materials, catalytic materials for clean energy conversion and storage, and other related topics. Part Three describes how to mimic natural materials processes to synthesize materials with low cost, efficient and environmentally friendly approaches. For each chapter, the approach is to describe situations in nature first and then biomimetic materials, fulfilling the need for an interdisciplinary approach which overlaps both engineering and materials science.
