Notes

This class implements material properties for AISI 4340 steel, a high-strength alloy steel commonly used in aerospace applications. The properties are based on median values.

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
