  We investigate the failure characteristics of complex networks within the
framework of the fiber bundle model subject to the local load sharing rule in
which the load of the broken fiber is transferred only to its neighbor fibers.
Although the load sharing is strictly local, it is found that the critical
behavior belongs to the universality class of the global load sharing where the
load is transferred equally to all fibers in the system. From the numerical
simulations and the analytical approach applied to the microscopic behavior, it
is revealed that the emergence of a single dominant hub cluster of broken
fibers causes the global load sharing effect in the failure process.
