Notes:
- e — edge distance (measured in the loading direction), D — diameter of the hole.
- When the direction of use is unknown, use the lesser of the applicable longitudinal or transverse properties.
- Allowable stresses for welded structures are generally lower than for unwelded. Heat from welding softens the HAZ.
Typical welded 6061-T6 values (ksi): Ftu 24, Fty 20, Fcy 20, Fsu 15, Fsy 12,
Fbru 50, Fbry 30.
Definitions:
A Basis: The lower value of either the statistically calculated T99 or the specification minimum (S-basis). T99 means at least 99% of the population is expected to meet or exceed the value with 95% confidence.
S Basis: Minimum values given in specifications; statistical basis not defined.
Longitudinal Direction: Parallel to the flow in a worked material (grain direction).
Long Transverse: Transverse direction with the largest dimension (width).
Short Transverse: Transverse direction with the smallest dimension (thickness).
Solution heat treatment: Heating to a suitable temperature, holding to dissolve constituents, and rapid cooling to retain them in solution.
Modulus of elasticity (Young’s modulus): Slope of stress–strain (tension/compression) within the proportional limit.
Poisson’s ratio: Ratio of lateral to longitudinal strain under uniaxial stress in the proportional limit.
Shear stress: Stress acting parallel to the cross-section (cutting nature).
Stress: Average force per unit area producing strain.
