Advantages

Load-bearing capacity increases with foam strength, tube wall thickness, and punch width

Energy absorption increases with foam strength, tube wall thickness, and punch width

The closer the loading position to the clamped end, the greater the improvement in load-bearing and energy absorption

Theoretical model can predict large deflection of metal FFTT under transverse loading
