Quasi-static oblique loading of AA6060 hollow sections

Description:
This set of files can be used to represent all tests in temper T4 from [reference] and can be used for validation purposes. The set up is thin-walled hollow sections in aluminium AA6060 tempers T4/T6 and subjected to quasi-static axial oblique loading.

Validation

For validation, we have used the following tests results (T4 temper only).

Comparison: Parameter Force (N) - at a cross-head displacement of 50 mm

Test Reference Numerical Error
S-T4-05-2.0 5 5 0.0 %
S-T4-05-2.5 8 8.2 2.5 %
S-T4-05-3.5 15 14.7 2.0 %
S-T4-05-4.5 27 26.6 1.5 %
Comments

Note that the force levels has been read off graphically from figures in the above reference. The loads also represent averages from 5, 15 and 30 degree obligue loading (all tests converge at the same load level for cross head displacement of 50 mm). The original article plots the force level as function of a "plastic cross head displacement". Above, we have used the actual cross head displacement for the comparison. This is assumed to be a small error.
