Materials
In this section, libraries of materials can be created.
A library is a JSON file with a name, a target, units, a reference temperature and a list of materials.
Target can be :
- Piping
- Structure
- Bolting
- Welding
Click the + Folder button to add a new folder, click the + File to add a new library or click the - button to remove the selected folder or an unused library (not defined in a specification).
You can also import materials from BEAMSTRESS.
You can also drag a file/folder on another folder.
Example : “ASME II Part D 2008”
To know the UNIT of a property, just let the mouse over the property name.
For example : °C for the Ref. temperature
Click the + button (next to Materials) to add a new material or click the - button (next to Name) to remove one.
Define the description, the type, the thermal expansion option, the temperature max, the density and the Poisson’s ratio.
Click the + button (next to Properties) to add a new row of properties for a specific temperature or click the - button (end of row) to remove one.
