class Aluminum_Alloy(Solid):
"""
A class representing an aluminum alloy and its material properties.
Attributes
----------
density : float
Material density in kg/m³ (2700)
thermal_conductivity : float
Heat conduction coefficient in W/(m·K) (202.4)
specific_heat_capacity : float
Specific heat at constant pressure in J/(kg·K) (871)
ultimate_tensile_strength : float
Maximum tensile stress before failure in Pa (310e6)
ultimate_shear_strength : float
Maximum shear stress before failure in Pa (206e6)
ultimate_bearing_strength : float
Maximum bearing stress before failure in Pa (607e6)
yield_tensile_strength : float
Stress at which material begins to deform plastically in Pa (276e6)
yield_shear_strength : float
Shear stress at which material begins to deform plastically in Pa (206e6)
yield_bearing_strength : float
Bearing stress at which material begins to deform plastically in Pa (386e6)
minimum_gage_thickness : float
Minimum manufacturable thickness in m (0.0)
minimum_width : float
Minimum width in m
Notes
-----
This class implements standard 6061-T6 aluminum properties for both structural
and thermal applications. The thermal properties are particularly relevant for
battery cooling applications.
**Definitions**
'Ultimate Strength'
The maximum stress that a material can withstand before failure
'Yield Strength'
The stress at which a material begins to deform plastically
'Thermal Conductivity'
The property of a material to conduct heat, measured in watts per meter-kelvin
