ISOGRID-SST™ generates layouts and properties of three skin frame structures. It computes the shown effective skins in these Z-frame cross sections.

ISOGRID-SST™ optimizes the frame design accounting for general instability, skin buckling and skin diagonal tension.

Isogrid, waffle or a skin stringer can be used in place of the shown frames and skins.  The skin can be replaced with an isogrid, waffle or skin stringer structure and the frame with an isogrid or waffle annulus. ISOGRID-SST™ can size and design such structures.
