PhD FEM modelling of deterioration behavior of sewer systems

Eindhoven University of Technology, the Netherlands, is looking for a PhD Finite element modelling of deterioration behavior of sewer pipe systems.

Position: PhD-student

Departments: Department of the Built Environment

FTE: 1,0

Date off: 12/02/2017

Reference number: V38.2809

Job description

Condition-based asset management of sewer systems lacks the availability of an accurate model to calculate the ultimate load bearing capacity of old sewer pipes, deteriorated by e.g., biochemical corrosion. An advanced finite element method (FEM) model will be developed taking into account full soil-pipe interaction as well as the nonlinear behaviour of a sewer due to localised cracking. This model should support operators in estimating the risk of keeping an ancient pipe in service under present and future loading conditions. The model will be verified and calibrated extensively by means of photo-elastic research on the soil model, large scale loading tests on old sewer pipes, and loading tests in a geo-centrifuge on fully embedded sewer pipe systems. A parametric interface will be developed in order to simplify the usage of the advanced models, and to conveniently allow for the performance of Monte Carlo simulations that account for the spread and uncertainty in input parameters.

The PhD research will be embedded in the Applied Mechanics and Design (AMD) group and the Concrete Structures (CS) group of the unit Structural Design in the Department of the Built Environment, TU Eindhoven. A strong collaboration will take place with the Urban Drainage group at the Faculty of Civil Engineering at the TU Delft and the section Geo-engineering at Deltares. The focus of the PhD research lies on the development and validation of an advanced FEM model for the calculation of the structural behavior of a sewer pipe system, and to predict baseline conditions for risk-based asset management. The PhD should further collaborate with and support a post-doc, who in the project performs the experimental tests of deteriorated cementitious sewer pipe systems.
