class Magnesium(Solid):
"""
A class representing RZ5 magnesium alloy material properties per BS 2L.128 standard.
Attributes
----------
ultimate_tensile_strength : float
Maximum tensile stress before failure in Pa (200e6)
ultimate_shear_strength : float
Maximum shear stress before failure in Pa (138e6)
ultimate_bearing_strength : float
Maximum bearing stress before failure in Pa (330e6)
yield_tensile_strength : float
Stress at which material begins to deform plastically in Pa (135e6)
yield_shear_strength : float
Shear stress at which material begins to deform plastically in Pa (138e6)
yield_bearing_strength : float
Bearing stress at which material begins to deform plastically in Pa (130e6)
minimum_gage_thickness : float
Minimum manufacturable thickness in m (0.0)
density : float
Material density in kg/m³ (1840)
Notes
-----
This class implements material properties for RZ5 magnesium alloy, which is commonly
used in aerospace applications due to its high strength-to-weight ratio. The zero
value for minimum gage thickness indicates that this should be specified based on
specific manufacturing capabilities.
**Definitions**
'RZ5'
A magnesium alloy designation per British Standard BS 2L.128, containing zinc
and rare earth elements for improved strength
'Ultimate Strength'
The maximum stress that a material can withstand before failure
'Yield Strength'
The stress at which a material begins to deform plastically
