UE01 Classifications of Materials Basic Terminology

• Potential Energy

• Kinetic Energy

• Mechanical Energy

• Thermal Energy

• Nuclear Energy

Equals the amount of energy needed to raise the temperature of 1g water by 1K at atmispheric pressure.

• Ashby diagrams compare tow different material properties in one diagram

• each material is represented by a data point

• therefore material classes are summarized in bubbles which makes it possible to compare material classes with regard to their properties

+ Ashby diagrams are a useful tool for optimized material selection given specific requirements and restrictions

+ mostly two material properties are plotted against each other (e.g. Modulus vs. Density)

length at wich a freely hanging cross section of a material breaks off due to its own weight at the fastening
