9. The cargo body of claim 8 , wherein the second panel edge portion is recessed into the exterior side of the first panel.
10. The cargo body of claim 1 , wherein, in each of the first and second panels, the thickness of the core between the interior and exterior skins at the full-thickness core section is more than 20 times the material thickness of the metal sheet of which the core is formed.
11. The cargo body of claim 1 , wherein the joint is formed by adhesively bonding the first panel edge portion to the second panel and adhesively bonding the second panel edge portion to the first panel.
12. The cargo body of claim 1 , wherein one or both of the first and second panel edge portions receive a plurality of mechanical fasteners to secure the joint.
13. The cargo body of claim 1 , further comprising a roof and a floor, both of which cooperate with a sidewall formed at least in part by the first and second panels to define a cargo receiving volume of the cargo body.
14. A jointed multi-panel cargo body wall comprising:
a first panel having a composite construction including an interior skin, an exterior skin, and a core positioned between the interior and exterior skins, wherein the core is a metal sheet of anticlastic form having an array of interspersed peaks and valleys; and
a second panel having a composite construction including an interior skin, an exterior skin, and a core positioned between the interior and exterior skins, wherein the core is a metal sheet of anticlastic form having an array of interspersed peaks and valleys,
wherein the first and second panels are secured together at a mutual joint including a first panel edge portion of the first panel and a second panel edge portion of the second panel,
wherein the first panel edge portion includes one or both of the interior and exterior skins extending onto an interior side of the second panel, and the second panel edge portion includes one or both of the interior and exterior skins extending onto an exterior side of the first panel, and
wherein a full-thickness core section of the first panel core terminates prior to and does not extend into the first panel edge portion, and a full-thickness core section of the second panel core terminates prior to and does not extend into the second panel edge portion.
15. The jointed multi-panel cargo body wall of claim 14 , wherein the interior skin of the first panel overlaps the full-thickness core section of the second panel, and wherein the exterior skin of the second panel overlaps the full-thickness core section of the first panel.
16. The jointed multi-panel cargo body wall of claim 14 , wherein the cores of the first and second panels are separated by a portion of the exterior skin of the first panel and/or a portion of the interior skin of the second panel.
17. The jointed multi-panel cargo body wall of claim 14 , wherein the core of the first panel terminates and does not extend into the first panel edge portion, and wherein the core of the second panel terminates and does not extend into the second panel edge portion.
18. The jointed multi-panel cargo body wall of claim 14 , wherein the first edge portion is a multi-layer flange defined by overlapping portions of the core and both the interior and exterior skins.
