17. A side panel for use in a crash attenuator or a guardrail, the panel having a predetermined width, a predetermined length, and a plurality of angular corrugations comprised of a first plurality of flat ridges, a second plurality of flat grooves, and a third plurality flat slanted middle sections extending between the ridges and grooves, each of the side panels further comprising
a plurality of first gussets mounted on a structural member supporting the side panel so as to be positioned under a top flat ridge and a bottom flat ridge of the plurality of flat ridges, and
a plurality of second gussets mounted on the structural member, each of the second gussets being attached to a corresponding first gusset to reinforce the first gusset.
18. The side panel recited in claim 17 , wherein there is a gap between each of the first ridges and a corresponding one of the first gussets positioned underneath the first ridge.
19. The side panel recited in claim 17 , wherein each of the first gussets is a trapezoidal-shaped plate connected to the support member.
20. The side panel recited in claim 19 , wherein each of the second gussets is a triangular-shaped plate that is connected to the structural member and to a corresponding first gusset to reinforce the first gusset.
21. A panel comprising a plurality of angular corrugations comprised of a first plurality of flat ridges, a second plurality of flat grooves, and a third plurality flat slanted middle sections extending between the ridges and grooves, a portion of each ridge's trailing edge being bent in toward a succeeding ridge to preclude reverse impact snagging by a trailing edge of the panel.
22. The panel recited in claim 21 , wherein the middle sections connecting the ridges to adjacent grooves each having a curved portion to accommodate the bent portion of each ridge's trailing edge and to prevent reverse impact snagging by the trailing edge of the panel.
