摘要
In this paper, hydrogen-induced delamination of a bulk material with a finite thickness is investigated. Hydrogen implanted interface splitting is considered as the growth of the crack by forming blisters. The radius of a blister depends on the amount of the implanted hydrogen, crack surface energy, and annealing temperature. For a finite thickness of the superstrate, the evolution of the blisters is calculated adopting a smooth bell-shape function and applying the Rayleigh-Ritz method [K. K. Raju and E. V. Rao, J. Eng. Mech. 119, 626 (1993)]. The required minimum implanted gas N-min is calculated accordingly. The calculated N-min value is compared with an experimental result in literature.
