ABSTRACT
This paper initially gives general steps of flow-cum-crack analysis using three-dimensional 32 nodded isoparametric elements together with line and bond-linkage elements. An endochronic model is used in which a provision is made for the increment of inelastic dialatancy variable, shear and bulk moduli. A set of material parameters obtained by fitting numerous test-data is used for the non-linear analysis of the Oldburg containment vessel. The endochronic model is then extended and is linked to a cracking analysis within the computer program OBAID. Certain analytical results such as displacements for low and high pressure-over pressurization are obtained. The results show agreement in certain areas with those obtained by other and some disagreement at other areas of the solution domain.
