Postdoctoral scholarship – Experimental mechanics of cellulose nanocomposites

KTH Royal Institute of Technology

Stockholm, Sweden

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

The workplace
Division of Biocomposites, Dept. of Fiber and Polymer Technology: www.kth.se/fpt/biocomposites Focus is on nanostructured composite materials, in particular with nanocellulose as one component. The scientific interest is on relationships between processing and structure, and between structure and properties. Materials include nanocellulose, plant fibers, wood, biopolymers, and material systems such as aerogels, foams, biocomposites, polymer matrix nanocomposites, inorganic hybrids etc. The post doctors will work directly with Professor Lars Berglund.

Project Description
In this project, the focus is experimental mechanics of cellulose nanomaterials. The main experimental technique is strain field measurements using digital image correlation, DIC. We are interested in deformation and failure mechanisms in a variety of materials based on cellulose nanofibrils but also wood fibers. Mechanical properties will be measured, in different types of tensile, compression and shear tests, as well as fracture mechanics methods. The larger program is funded by Knut and Alice Wallenberg’s foundation, and about 10 PhD students and post doctors are involved with 5-7 faculty. The long-term interest is in eco-friendly and multifunctional high-performance materials from cellulose.

The post doctors will investigate the mechanical behavior of cellulose materials and composites. Important questions are related to fiber/fibril orientation effects, inhomogeneities in the form of agglomerates and porosity, and relationships between micro/nanostructure, deformation mechanisms and properties.

The applicant must have completed a doctoral degree in a subject related to mechanics of materials or structural engineering. A doctoral degree must have been obtained within three years when applying for this postdoctoral scholarship.

We seek candidates with a background in mechanics or mechanical behavior of materials/structures, including experimental studies. Previous experience of strain field measurement techniques is advantageous but not necessary. Data reduction and interpretation is important, which require numerical analysis skills, for instance experience from using MATLAB®.

The candidate should be structured and creative, be able to work independently at high pace, meet agreed deadlines, with good abilities in critical thinking and a good publication record. You should have good communication skills, with ability to have deep scientific discussion in English. Composite materials competence is an advantage. Great emphasis will be placed on personal competence and suitability.
