The CD-ROM Molecular Dynamic Simulation contains the following components:

 

1. Solidification: 
This program simulates particles in a box with a fixed volume. Depending on the temperature the particles may appear as a gas, liquid or a crystalline solid.

 

2. pV-Diagram: 
This program is an extension of the program solidification. We are still looking at particles in a box but now the box is closed on the top by a movable piston which - through its weight - guarantees a fixed pressure. A typical experiment proceeds by lowering that pressure in small steps at a constant temperature. The mean volume is calculated and what results is an isotherm in a (p,V)-diagram. The interesting feature to be demonstrated is the transition of the isotherm through the wet steam region of the diagram.

 

3. Rubber: 
The program simulates the behavior of a rubber molecule composed of a chain of up to 100 connected links. The molecule is fixed at one end and at the other end it may be subject to three different vertical loads, one of them being zero. Thus the chain can be observed in its function as an entropic spring.
The spring properties may be influenced by temperature and the size of the load at the end. Under proper manipulation of the weight the molecule may simulate a harmonic oscillator.

 

4. Play Animation: 
The films demonstrate the visualization of phase transitions in shape memory alloys.
This program is free software designed by Oliver Kastner. See also copyright.txt in the folder 'films'.
