A stochastic approach, the Ising model combined with Monte Carlo simulation, is employed to study the process of a fiber debonding and being pulled out from a fiber reinforced composite. The complicated mechanisms involved can be realistically simulated more than ever with a simple algorithm that is applicable to such phenomena as partial debonding, fiber breaking and matrix yielding, all of wh...

The main objective of this study is to provide a parametric evaluation of the pull-out work of smooth steel fibers embedded in cementitious matrices. The various parameters controlling the behavior of the bond stress versus slip relationship are analyzed; their effects on the entire pull-out load versus slip response and the corresponding pull-out energy up to full debonding and~or up to total ...

This study investigated the fracture resistance and retention of endodontically treated roots with over-flared canals restored with different post systems, including one cast metal post and four fiber posts with/without auxiliary fiber posts. One hundred endodontically treated incisor roots were experimentally flared using a tapered diamond bur. The roots were restored using one of the five pos...
