Exactly Agaricus. I can do the physics. I got an "O" level...

Luke Sky Toddler: "Wiz it's not just the total G pulled it's how fast the G came on ... they plot G vs time in 0.1 second increments and there's a huge chart they have to refer to to calculate the severity from that."

This makes no sense.

"G" pulled refers to acceleration equal to gravity. This is approx. 9.8 meters per second per second. 2.3G is therefore an acceleration of 22.54 meters per second per second. The force of this can be calculated as newtons per kg of mass of the body accelerating...

Take an average landing weight of a 330 to be 150 tonnes... that will mean the gear was loaded with 3.4 million newtons of force. (the G will have peaked when the bird hit I am presuming... I doubt they damaging the bird with aerobatics). Brand B may be "weak"... but that gives you an idea of the forces involved.
