class Paint(Solid):
"""
A class representing paint and vinyl surface coating material properties.
Attributes
----------
ultimate_tensile_strength : float
Maximum tensile stress before failure in Pa (0.0)
ultimate_shear_strength : float
Maximum shear stress before failure in Pa (0.0)
ultimate_bearing_strength : float
Maximum bearing stress before failure in Pa (0.0)
yield_tensile_strength : float
Stress at which material begins to deform plastically in Pa (0.0)
yield_shear_strength : float
Shear stress at which material begins to deform plastically in Pa (0.0)
yield_bearing_strength : float
Bearing stress at which material begins to deform plastically in Pa (0.0)
minimum_gage_thickness : float
Minimum applicable thickness in m (150e-6)
density : float
Material density in kg/m³ (1800)
Notes
-----
This class implements material properties for paint and vinyl surface coatings.
The zero values for strength properties reflect that these coatings are non
load-bearing elements. The minimum gage thickness represents a typical
coating thickness for aerospace applications.
**Definitions**
'Surface Coating'
A material applied to the surface of another material to provide protection,
decoration, or other functional properties
'Minimum Gage Thickness'
The minimum thickness required for adequate surface coverage and protection
