Notes
-----
This class implements material properties for Ti-6Al-4V (Grade 5) titanium alloy
in the annealed condition. This alloy is widely used in aerospace applications
due to its excellent strength-to-weight ratio and corrosion resistance.
**Definitions**
'Ti-6Al-4V'
A titanium alloy containing 6% aluminum and 4% vanadium, also known as Grade 5
'Ultimate Strength'
The maximum stress that a material can withstand before failure
'Yield Strength'
The stress at which a material begins to deform plastically
