PhD position: Multi-scale Modelling and Experimental Assessment of Volumetrically Prestressed Concrete

The tasks of the PhD at ETHZ and Empa within the framework of SURPASS are as follows: Volumetric prestressing of cast and 3D-printable SURPASS overlays using Fe-SMA fibres. Meso-scale finite element modelling of volumetric prestressing mechanisms with Fe-SMA fibres, including activation, recovery stress, prestress transfer, and reactivation. Structural-scale simulation of SURPASS overlays in strengthened members, including parametric finite element analyses for surrogate-model development and digital-twin support. Large-scale experimental assessment of volumetrically prestressed SURPASS overlays for non-planar structures, including representative applications such as tunnel linings, arch intrados, and curved bridge soffits.

Materials science and technology are our passion. With our cutting-edge research, Empa's around 1,100 employees make essential contributions to the well-being of society for a future worth living. Empa is a research institution of the ETH Domain. Smart and Sustainable Resilient Performance-based Cementitious Composites for Adaptive Strengthening and Repair System (SURPASS) is an EU Research and Innovation project (2027-2031) which aims to develop adaptive strengthening and repair strategies for ageing infrastructure in aggressive environments. The project comprises 11 partners across the globe, including partners from Europe, Canada and Japan.
