Dissemination of IT for the Promotion of Materials Science (DoITPoMS)

DoITPoMS TLP Library

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.

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.

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.

Dielectric Materials

This teaching and learning package will introduce you to the properties and uses of dielectric materials.

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.

Ferromagnetic Materials

How many ferromagnets do you think you own? Maybe many more than you realise. Ferromagnetic materials lie at the heart not just of the humble compass, but also of many loudspeakers and of computer memory. This teaching and learning package outlines the microscopic basis of magnetism and some of the conquences of ferromagnetic order in real materials.

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.

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.

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.

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.

Tensors in Materials Science

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.
