class Nickel(Solid):
"""
A class representing nickel alloy material properties.
Attributes
----------
ultimate_tensile_strength : float
Maximum tensile stress before failure in Pa (1830e6)
ultimate_shear_strength : float
Maximum shear stress before failure in Pa (1050e6)
ultimate_bearing_strength : float
Maximum bearing stress before failure in Pa (1830e6)
yield_tensile_strength : float
Stress at which material begins to deform plastically in Pa (1550e6)
yield_shear_strength : float
Shear stress at which material begins to deform plastically in Pa (1050e6)
yield_bearing_strength : float
Bearing stress at which material begins to deform plastically in Pa (1550e6)
minimum_gage_thickness : float
Minimum manufacturable thickness in m (0.0)
density : float
Material density in kg/m³ (8430)
Notes
-----
This class implements material properties for nickel alloy based on
median values from manufacturer reported data. The zero value for minimum gage thickness
indicates that this should be specified based on specific manufacturing capabilities.
**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
