Sažetak
The increasing application of polymeric materials especial polyethylenes as structural materials demands new methodologies in order to assess the material capability to withstand loads. The use of medium density polyethylene pipes for water and gas distribution is one of the most common examples. An accurate modeling of fracture and viscoelastic material responses of such structures, represent a key for the prediction of structural integrity. Since the polyethylene structures are mostly subjected to creep loadings, the present paper is concerned with the numerical modeling of creep fracture mechanisms by slow crack growth [1]. The finite element code ABAQUS [2] is used for analyzing the creep deformation and the fracture parameters from small-scale creep to steady-state creep conditions.
