About the position

In this position you will work in an interdisciplinary environment with strong computational mechanics, geotechnical and rock mechanics groups. It gives a possibility to conduct advanced research on the response of civil infrastructure subjected to blast and impact loading. The project combines computational mechanics, nonlinear finite element analysis and soil–structure interaction to address critical challenges in civil protection and societal resilience.

Are you motivated to take a step towards a doctorate and open up exciting career opportunities? As a PhD Candidate with us, you will work to achieve your doctorate, and at the same time gain valuable experience that qualifies you for a further career in higher education and research, in and outside academia.

Your immediate leader will be the Head of Department.

About the project

The project investigates whether existing civil infrastructure can provide adequate protection against blast and impact threats arising from modern warfare scenarios, including missile and drone attacks. Particular emphasis will be placed on understanding structural response, failure mechanisms and collapse resistance of typical building structures, underground facilities and other critical infrastructure.

The research will combine advanced finite element simulations, blast loading models, propagation of pressure waves in the ground and soil–structure interaction analyses to establish methods for assessing the protective capacity of existing infrastructure and identifying effective strengthening measures. Selected existing structures will be used as case studies.

A central aspect of the project is to identify how wave propagation in soil and soil–structure interaction influences the vulnerability or robustness of infrastructure. The candidate will investigate how soil stiffness, layering, and water saturation conditions modify the distribution of blast loads and affect potential failure mechanisms. This includes studying scenarios where underground structures provide shielding effects, as well as cases where wave reflection or confinement may increase local damage. In addition to numerical research, the PhD candidate will contribute to experimental investigations of geomaterials subjected to high strain rates. Laboratory testing will be used to characterize the dynamic properties of soil and rock, providing essential input for model calibration and validation. 

The project addresses emerging challenges related to civil preparedness and protection of critical infrastructure in a rapidly changing security environment. The project is carried out with an accompanying PhD project in computational mechanics that will focus on numerical simulation of fluid-structural interaction under blast loading.

Duties of the position
