PhD position: friction in architected materials

100%, Zurich, fixed-term

The Computational Mechanics of Building Materials in the Institute for Building Materials at ETH Zurich has an opening for a PhD candidate infriction in architected materials.

Project background

The Computational Mechanics of Building Materials (CMBM) aims to understand and predict mechanical failure in materials and structures. By combining numerical modeling tools with tailored laboratory experiments and theoretical models, we create a holistic perspective on mechanical failure, bridging the gap between material behavior at the small scale and principles governing catastrophic failure at the system level. CMBM is a highly interdisciplinary and international research team. The topics of current research projects at CMBM include uncovering the mechanisms of earthquake nucleation and arrest, building structures with topologically interlocked materials, revealing the processes governing the structural build-up of cement in additive manufacturing, determining the nano- and micro-scale processes that control cracking of concrete due to corrosion, uncovering the fundamental laws governing granular materials, and revealing the damage and fracture mechanisms in soft materials.

This position is part of a project funded by the Swiss National Science Foundation, which supports multiple researchers and focuses on the development of interfaces with unconventional mechanical properties.

Meta-materials, which are architected materials with properties resulting from their meso-structure, have gained increasing attention in recent years because of their unconventional and superior mechanical properties. While many meta-materials are designed to have unique dynamic properties, great resistance to damage, or outstanding toughness-density ratios, research on their frictional properties has been limited. In this project, our aim is to explore the mechanical properties of interfaces in architected materials with a particular focus on friction. We aim to establish the necessary understanding of friction at meta-interfaces that will enable the design of unconventional friction properties.

Job description

The successful candidate will develop numerical and theoretical models to determine the friction properties of meta-interfaces. She/he will evaluate the mechanical properties resulting from various architected meso-structural approaches using in-house codes and high-performance computing systems. He/she will analyze the produced data to determine the factors leading to desired friction properties and establish knowledge that provides the scientific basis for the development of architected material concepts for unconventional friction behavior. The candidate will actively collaborate with (external) collaborators in experimentally testing the design concepts and demonstrate their potential.
