Evaluate the impact on pipe performance and life expectancy of the transition (1991) from wall thickness class to pressure class designations in the manufacture and design standards for ductile iron pipes. Study and compare historical failure rates of ductile iron pipes in a geographically diverse group of water utilities from North America and Australia. Evaluate reliability and capabili...
The gravitational deformation of volcanoes is largely controlled by ductile layers of substrata. Using numerical finite-element modelling we investigate the role of ductile layer thickness and viscosity on such deformation. To characterise Ž . Ž the deformation we introduce two dimensionless ratios; P volcano radiusrductile layer thickness and P viscosity of a b . ductile substratumrfailure str...
It is well known that when coarse-grained metals undergo severe plastic deformation to be transformed into nano-grained metals, their ductility is reduced. However, there are no ductile fracture criteria developed based on grain refinement. In this paper, we propose a new relationship between ductile fracture and grain refinement during deformation, considering factors besides void nucleation a...
J. Cárcel-Carrasco; M. Pascual; M. Pérez-Puig; F. Segovia. ITM-Universitat Politècnica de València (Spain). Camino de vera s/n, 46022 Valencia (Spain). Corresponding author, Email: [email protected] This work compares the weldability of ductile iron when: (I) a root weld is applied with a tungsten inert gas (TIG) process using an Inconel 625 source rod and filler welds are subsequently applie...
