Introductory description

The focus of this module is on enabling students to undertake a systematic materials selection process, taking account of the required performance, constraints, objectives, cost and environmental implications for engineering components. Selecting the wrong material can be as bad as any other poor decision when designing engineering products or systems. Poor materials choices can lead to non-competitive or environmentally damaging products and, in the worst cases, catastrophic failures.
Materials selection involves: the translation of functional requirements into materials performance objectives; the screening of materials that do not meet these objectives; the development of performance indices to rank candidate materials; and refining down to a single optimal material taking cost and environmental factors into account.

Module aims

The aim of this module is to equip students with the knowledge and technical skills required to undertake a systematic materials selection process (primarily for structural, mechanical problems), with the aid of traditional engineering data sheets and computer-aided engineering (CAE) tools. Students’ appreciation of engineering data will be supported by laboratory activities from which they will learn and experience how fundamental measurements of mechanical properties of materials are carried out.

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
Introduction to engineering materials and materials selection.
Case studies that introduce students to materials selection (translation, screening, ranking, refining) based on fundamental mechanical properties (such as stiffness, strength and toughness), cost and sustainability factors.
Strengthening mechanisms of common engineering materials (such as bonding, grain size strengthening, solid solution strengthening, precipitation strengthening and work hardening).
Basic failure mechanisms of structural engineering materials (such as plasticity, fracture and fatigue), supported by laboratories in which these mechanisms and related properties will be measured for different engineering materials.

Learning outcomes

By the end of the module, students should be able to:

  • Qualitatively describe the main stages of a systematic materials selection process, how it links with the Engineering Design Process, and the importance of lifecycle of a product and global context of optimising materials selection for a variety of engineering applications with consideration of economic and environmental drivers C7(D) M7(D).
  • Describe the characteristic properties of different major families of engineering materials such as metals, ceramics, polymers and hybrids, with reference to fundamental differences in their underlying microstructure C13 M13.
  • With the aid of a CAE tool (such as Edupack) and technical literatures (such as engineering data sheet book), combine fundamental theory and performance requirements, along with cost and simple measures of environmental impact (such as embodied energy) to carry out a materials selection process for a broadly-defined engineering application C4(D) M4(D).
  • Describe the strengthening mechanisms found in structural engineering materials and identify how these are connected to their mechanical properties (such as stiffness, strength and toughness) C13 M13.
  • Describe typical failure mechanisms of structural engineering materials and be able to perform calculations to predict failure mechanisms for broadly-defined engineering applications C13 M13.
  • Demonstrate a knowledge of how fundamental mechanical properties of engineering materials are measured and appreciate the link between experimental data and engineering design data found in data sheets and CAE tools C4 ( D) M4 (D) C13 M13.
