Designing sheet metal parts to reduce weight

Sheet metal parts may be shrewdly stiffened using pressed or formed features, without having to increase plate thickness. The images below show simple pressed features which act to increase the section of a flat part in order to give it significantly higher stiffness without increasing weight.

Of particular importance to parts under bending or buckling loads, this effectively improves the section properties, namely the second moment of area, and can do wonders for the aesthetic appeal of a part.
