2.6 My Environments

\includegraphics[width=14pt]{./Images/Environment.png} My Environments hold the temperature and moisture changes that the laminate will see in service. CADEC treats these environmental effects as loads. They are very important for composites design.

An Environment is an object that contains a temperature deviation and a moisture deviation. Both deviations are taken with respect to the state of the material for which the material properties were measured. So, if the properties were measured at standard ambient temperature (SAT, 25 Celsius), and the operating temperature for your project is different, the difference is $\Delta T$=operation temperature minus SAT. For moisture, $\Delta m$ is the moisture intake from standard to operation conditions.
