We examine the confined elastic buckling of a single N-particle force chain. For a given set of material parameters, a characteristic load-carrying capacity is attained for a clearly defined range of force chain lengths N ≥ L*. The rotation and translation of particles along periodically located segments of the critical buckling mode, each of length L*, are on average consistent with those for particles...
A personal overview of the buckling process is given, based on more than 30 years research experience. A fundamental distinction is drawn between structures that tend to distribute their pattern of buckling over the entire available length, and those that favour limiting it to a localized portion. Difficulties are compounded by the fact that localized solutions typically are shadowed by distributed...
