Systems and methods for evaluating rigidity of angle bracket

A method for evaluating a rigidity of an angle bracket, comprising:

• engaging an angle bracket coupon with a first test fixture and a second test fixture, the angle bracket coupon configured to correspond to the angle bracket;
• the angle bracket coupon including a first wall, a second wall coupled to the first wall at a bend to define an angle between the first wall and the second wall, the first wall terminating at a first end or the first wall connected to a first support wing extending outwardly at an obtuse angle from the first wall, the second wall terminating at a first end or the second wall connected to a second support wing extending outwardly at an obtuse angle from the second wall, and at least one three dimensional feature defined at the bend that extends between the first wall and the second wall, and the first test fixture engaging the bend or engaging the first end of the first wall and the first end of the second wall or engaging at least one of the first support wing or the second support wing, and the second test fixture engaging the bend or engaging the first end of the first wall and the first end of the second wall or engaging at least one of the first support wing or the second support wing;
• moving, by a test system, the first test fixture relative to the second test fixture;
• measuring, by the test system, a force and a displacement associated with the angle bracket coupon;
• and
• outputting data of the measuring of the force and the displacement.
