TLP Library
Teaching and learning packages (TLPs) are self-contained, interactive resources, each focusing on one area of Materials Science.
TLPs containing HTML5 animations/simulations are labelled with the tag 
. We have found that often the HTML5 animations render better in Microsoft Edge, so if your favourite browser does not work very well with them, please try an alternative.

Having the following tags:
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.
Brillouin Zones
This teaching and learning package provides an introduction to Brillouin zones in two and three dimensions and is aimed at developing familiarity with Brillouin Zones. It will not cover any specific applications. Brillouin Zones are particularly useful in understanding the electronic and thermal properties of crystalline solids.
Coating Mechanics
This TLP should provide some insights into the mechanics of bi-layer (coating on substrate) systems. It covers the concept of a misfit strain and the way in which equilibrium is established after its introduction, including the creation of curvature. The differences between "thin" and "thick" coating cases are explained.
Crystallographic Texture
This teaching and learning package (TLP) introduces the concept of texture in crystalline materials such as common metals and metallic alloys.
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.
Dielectric Materials
This teaching and learning package will introduce you to the properties and uses of dielectric materials.
Diffraction and Imaging
A brief summary of diffraction and imaging using an optical system.
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.
Ferroelectric Materials
Ferroelectrics have been used in real-world applications for a small number of decades, most notably for non-volatile data storage. For example, they have been used in a Sony Playstation and Japanese railway cards.
Indexing Electron Diffraction Patterns
An introduction to the indexing of diffraction patterns.
Introduction to Mechanical Properties of Materials
This teaching and learning package (TLP) introduces mechanical properties of materials, starting from a stress–strain curve and exploring both elastic behaviour (e.g., Hooke's law) and plastic behaviour (e.g., slip, creep).
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.
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.
Piezoelectric Materials
This teaching and learning package (TLP) provides an introduction to piezoelectric materials.
Pyroelectric Materials
Pyroelectric materials are found in almost every home, in the form of intrusion detectors and other devices, and this TLP will consider how they work, and what the most common ones are made of.
Reciprocal Space
This TLP shows the construction of reciprocal lattices from real ones, use of the Ewald sphere for diffraction experiments and some other applications of reciprocal space.
Introduction To Semiconductors
This teaching and learning package provides a very basic introduction to semiconductors. These materials are essential to the operation of solid state electronic devices.
The Stereographic Projection
This TLP covers the use of the Stereographic projection and Wulff nets.
Superconductivity
Electrons in pairs? Levitating trains? Superconductivity - the combination of lossless electrical conduction and the ability of a material to expel a magnetic field - is a property that excites interest in fundamental science whilst offering tantalising prospects for a range of applications. In this teaching and learning package (TLP), we trace the history of superconductivity, outline some fundamental properties of superconductors, and describe current and potential applications of materials with this unusual property.
Superelasticity and Shape Memory Alloys
This teaching and learning package (TLP) introduces the phenomena of superelasticity and the shape memory effect.
Introduction to thermal and electrical conductivity
This teaching and learning package (TLP) provides an introductory guide to both electrical and thermal conduction. It includes a few of the basic mechanisms of conduction, some useful formulae, and some common applications of electrical and thermal conductors and insulators.
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 Youngs 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.
X-ray Diffraction Techniques
This teaching & learning package provides an introduction to X-ray diffraction. It describes the main crystallographic information that can be obtained and experimental methods most commonly used.
