"Engineering the Application of Materials"

We have created a number of MathCAD based tools for solving typical materials science problems generically. Convert easily between weight, mole and volume fractions for any number of components. Download MathCAD file. Explore the 3rd law of thermodynamics. Determine Entropy, Enthalpy and Free Energy of reactions using heat capacity data. Download ZIP archive containing MathCAD file and example Cp data in Excel format. Determine the stress distribution and the stress at the root of a cylinder as a fluid flows past it. You might like to try this assuming the cylinder is your leg and the fluid is water in a fast moving stream. We used it to evaluate the stress acting on newly solidified dendrite arms during casting.

The projections can even be rotated so that any pole is at the centre of the projection rather than the standard [001] pole. These tools demonstrate how to use matrix algebra to effect geometric and co-ordinate transformations. Download the MathCAD file for cubic crystals. Download the MathCAD file for all crystal systems. Zone refining is a process used to purify materials. This tool uses a simple conservation of mass model to redistribute the impurities into a small pool of liquid which is slowly swept along a bar of the material to be purified. Repeating the process several times results in the very high purities necessary to make modern semiconductor crystals. The model can be used to explore and design a zone refining process. Download the MathCAD file for zone refining. All the functions you need to explore the use of Mohr's Circle in 2-D and 3-D including how to find the principal stresses, Von Mises Stress, Mean Stress and Maximum Shear Stress. Download the MathCAD file forMohr's Circle.
