Analysis of Deformation Processes
This TLP builds upon the introduction to yield criteria covered in the Stress analysis and Mohr's circle TLP and introduces a range of methods commonly used to study metal forming processes.
Atomic Force Microscopy
Provides a brief introduction to atomic force microscopy (AFM), some of the ways it is commonly used and some of the problems faced.
Atomic Scale Structure of Materials
This teaching and learning package provides an introduction to crystalline, polycrystalline and amorphous solids, and how the atomic-level structure has radical consequences for some of the properties of the material. It introduces the use of polarised light to examine the optical properties of materials, and shows how a variety of simple models can be used to visualise important features of the microstructure of materials.
Avoidance of Crystallization in Biological Systems
This teaching and learning package discusses the two main environmental threats leading to crystallization in plants and animals, and the ways in which organisms have adapted to avoid this crystallization. As part of this discussion, there is coverage of some of the theory of nucleation and crystallization.
Batteries
This TLP investigates the basic principles, design and applications of batteries. It covers both primary and rechargeable batteries, how they work and how they may be used.
Bending and Torsion of Beams
This teaching and learning package provides an introduction to the mechanics of beam bending and torsion, looking particularly at the bending of cantilever and free-standing beams and the torsion of cylindrical bars.
Crystallinity in Polymers
An understanding of polymer crystallinity is important because the mechanical properties of crystalline polymers are different from those of amorphous polymers. Polymer crystals are much stiffer and stronger than amorphous regions of polymer.
Deformation of Honeycombs and Foams
Highly porous materials, such as honeycombs, foams and fibrous structures, are an important class of material in both synthetic and biological systems. They are used in many different ways, but their mechanical behaviour is often of great importance as they are pressed, bent, sat on or chewed. An important class of these materials can be considered as made up of cells, so-called cellular structures. Here we describe how these materials deform, elastically and irreversibly.

Elasticity in Biological Materials
This teaching and learning package (TLP) discusses the elasticity of biological materials. Whilst some show Hookean elasticity, the vast majority do not. Non-linear elasticity is considered, in particular J-shaped and S-shaped curves. Viscoelasticity is also discussed, using hair and spiders' silk as examples.
Electromigration
Electromigration is an ever-increasing problem as integrated circuits are pushed towards further miniaturization. The theory of the phenomenon is explained, including electromigration-induced failure and how it has been and can be minimized.
Ellingham Diagrams
The Ellingham diagram is a tool most often used in extraction metallurgy to find the conditions necessary for the reduction of the ores of important metals. This Teaching and Learning Package incorporates an interactive Ellingham diagram. This diagram can be used to quickly and simply find a range of thermodynamic data relating to many metallurgical reactions.
Fuel Cells
This teaching and learning package provides a short summary of four of the most promising fuel cell technologies. It gives a general overview of the field with focus on materials used (electrolytes and electrodes) and the mechanism of function (electrochemistry and thermodynamics).
Mechanics of Fibre-reinforced Composites
This teaching and learning package (TLP) gives an introduction to the nature of fibre-reinforced composite materials and their basic mechanical characteristics.
Microstructural Examination
This teaching and learning package (TLP) looks at how what we see in micrographs relates to equilibrium phase diagrams and cooling routes for alloy systems.
The Nernst Equation and Pourbaix Diagrams
This teaching and learning package (TLP) investigates the Nernst equation and Pourbaix diagrams, which are both important parts of electrochemistry and corrosion science.
Phase Diagrams and Solidification
Phase diagrams are a useful tool in metallurgy and other branches of materials science. They show the mixture of phases present in thermodynamic equilibrium. This teaching and learning package looks at the theory behind phase diagrams, and ways of constructing them, before running through an experimental procedure, and presenting the results which can be obtained.
Introduction To Photoelasticity
This tutorial is based on lab work within the Department of Materials Science and Metallurgy at the University of Cambridge. The tutorial provides an introduction to the topic of photoelasticity and preparation for lab work. Photographs illustrate many features of birefringence in polymers under polarised light.
Raman Spectroscopy
An introduction to the analysis of materials and chemicals by the Raman scattering of light.
Solid Solutions
This teaching and learning package is based on a practical used within the Department of Materials Science and Metallurgy at the University of Cambridge. The package is aimed at first year undergraduate Materials Science students and focuses on the different types of solid solution and the thermodynamic principles involved in understanding them.
Stress Analysis and Mohr's Circle
This teaching and learning package provides an introduction to the theory of metal forming. It discusses how stress and strain can be presented as tensors, and ways of identifying the principal stresses. Suitable yield criteria to treat metals and non-metals are also presented.
Superelasticity and Shape Memory Alloys
This teaching and learning package (TLP) introduces the phenomena of superelasticity and the shape memory effect.
Tensors
This TLP offers an introduction to the mathematics of tensors rather than the intricacies of their applications. Its aims are to familiarise the learner with tensor notation, how they can be constructed and how they can be manipulated to give numerical answers to problems.

Thermal Expansion and the Bi-material Strip
This teaching and learning package (TLP) is based on lab work in the Department of Materials Science and Metallurgy at the University of Cambridge. The TLP provides an introduction to the topic of thermal expansion, and its application, together with the different stiffness of materials, in the bi-material strip. The TLP leads you through experiments to measure Young's Modulus from the deflection of a cantilever beam, and to estimate the boiling temperature of nitrogen and the expansivity of a polycarbonate material from the curvature of a bi-material strip immersed in liquid nitrogen.
