Postdoc in Fracture Mechanics for Composite Sandwich Structures in Aircrafts

DTU, Department of Mechanical Engineering at theTechnical University of Denmark invites candidates for a position as Postdoc inthe field of Fracture Mechanics for Composite Sandwich Structures in Aircrafts.The Postdoc will be associated with the Lightweight Structures group at theSection for Solid Mechanics, one of six sections in the department. Theposition is available as soon as possible and preferably with a start date byApril 1st 2019 or earlier.

The Lightweight Structures group consists of around10-15 persons and is focused on research, education and innovation withinprimarily polymer based fiber reinforced composite structures within a broadspectrum of applications ranging from aircrafts, ships, offshore structures,vehicles and energy applications.

Currently the group is involved in an international researchcooperation network focused on damages in aircraft sandwich structures, where disbondingbetween the face sheet and core of the sandwich is a critical damage mode andthe main focus of the network.

The research and the postdoc position is co-funded bythe Federal Aviation Administration (FAA), but in close cooperation with TheNational Aeronautics and Space Administration (NASA), The National Institute ofAerospace (NIA), AIRBUS, Dupont, Fraunhofer IMWS and a number of other US andEuropean partners.

The group has over 15 years of experience, developingboth advanced fracture mechanical analysis as well as test methods to addressthe criticality of disbond damages in sandwich structures in relation to damagetolerance and structural damage assessment. The candidate will be extendingthis work and participate in on-going and coming research and development activitieswithin this research field.

Responsibilitiesand tasks
The Postdoc will be responsible for specific researchtasks within fracture mechanics analysis and testing of composite sandwichstructures in aircrafts.

The research activities will initially include one ormore of the following areas: 

    Advanced finite elementmodelling of disbond damaged sandwich structures within aircraft structuresusing fracture mechanical analysis routines.Experimental testing ofsandwich components and structures in aircrafts, as well as validation ofnumerical analysis methods against experimental results.Advanced fracturemechanics characterization testing in support of numerical analysis methods.Development ofstandardized fracture mechanics test standards for sandwich materials in closecooperation with international partners and standardization organizations (eg.ASTM and ISO).

The candidate will also participate in supervision of bachelor-, master-and PhD-level students in the group.

The Postdoc will be working independently, but inclose cooperation with both other members of the Lightweight Structures groupas well as both national and international partners in the research project andnetwork. The Postdoc will also have a close daily cooperation with thelaboratory staff in DTU Structural Lab – one of the most advanced and largesttest facilities of its type in Northern Europe.

Candidates should have a PhD degree or equivalent infracture mechanics, preferably within composite materials and/or structures,though the latter is not a requirement.

We also expect the candidate to possess a high degree of flexibility andself-motivation, which are desired skills at DTU. In addition, we expect thecandidate to be interested in collaboration, but also to work independently andtake personal responsibility for assigned work tasks. The candidate must also demonstratecommitment to an academic carrier in order to qualify for the Postdoc position.

It is expected that the candidate possess generalknowledge of composite mechanics – both at the material and structural lengthscale. Furthermore, the candidate must be able to document research activitywithin three or more of the following areas: 

    Fracture mechanicsComposite materialsand/or sandwich structures  Finite element analysisusing commercial FEM codes (ABAQUS, ANSYS etc.)Hands-on experiencewith material and/or structural testingAdhesive joints
