  In this work I have studied the effect of disorder and system size in fiber
bundle model with a certain range of stress redistribution. The strength of the
bundle as well as the failure abruptness is observed with varying disorder,
stress release range and system sizes. With a local stress concentration, the
strength of the bundle is observed to decrease with system size. The behavior
of such decrement changes drastically as disorder strength is tuned. At
moderate disorder, the critical stress scales with system size in an inverse
logarithmic manner. In low disorder, where the brittle response is highly
expected, the strength decreases in a scale free manner. With increasing system
size and stress release range the model approaches thermodynamic limit and the
mean field limit respectively. A detail study expresses different limit in the
model and the corresponding modes of failure on the plane of above mentioned
parameters.
