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.

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.
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.
This teaching and learning package (TLP) introduces the concept of texture in crystalline materials such as common metals and metallic alloys.
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.
A brief summary of diffraction and imaging using an optical system.
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.
An introduction to the indexing of diffraction patterns.
This teaching and learning package (TLP) gives an introduction to the nature of fibre-reinforced composite materials and their basic mechanical characteristics.
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.
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.
This TLP covers the use of the Stereographic projection and Wulff nets.
This teaching and learning package (TLP) introduces the phenomena of superelasticity and the shape memory effect.
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.
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.
