Based on novel bio-composite materials, this project aims at investigating the sustainability of structural components made from new materials relative to conventional composite materials. The sustainability of new and existing composite solutions will be quantified applying Life Cycle Impact Assessment (LCIA).

Ortopæd Ingeniørene har udviklet og produceret en dropfodsskinne ved navn Flexbrace®, som har været på marked i 8 år. Der ønskes en FEM af en dropfodsskinne i simplificeret form med henblik på at undersøge samspillet mellem geometri, materialer, belastninger og produktion. Med udgangspunkt i dropfodsskinnens funktion og geometriske begrænsninger skal der foretages en parameter undersøgelse af dropfodsskinnen. Parameterundersøgelsen vil omfatte en vurdering af anvendte materialer samt geometri i forhold til de mekaniske belastninger skinnen bliver udsat for af patienten
The project involves nonlinear finite element modeling using the commercial finite element code ABAQUS. The project involves using a newly developed user material subroutine and can ether include application of the model on specific problems or improvement of the implemented model.
Natural fibre composites have found increased international interest during the last decade. Traditionally, new materials have been developed in order to solve technological problems within the aerospace, military, sport or medicine fields, whereas natural fibre composites are also developed in another perspective; they must meet the demands in society of being sustainable materials.
Based on finite element models of specific suspicious skull fracture cases, a dynamic finite element simulation of the fracture process will be performed. The finite element model will be extracted from a CT-scan of the specific case and the simulation can e.g. focused on the influence on the spongius layer in the skull and the influence of a detailed dynamic cohesive element model on the subsequently crack predictions.
Arbejdet indebærer indsamling af luft-prøver i felten med henblik på at bestemme udledningen af drivhusgasserne lattergas (N2O) og metan (CH4). Der arbejdes i en nyetableret pile-beplantning, som dyrkes med henblik på produktion af biomasse til energiformål
The project studies the effects of multifactor climate change to plants. Effects are studied at different levels of the organism from genome over transcriptome to physiology, phenotype and lastly species interactions. Selected crop and model species are analysed. Interactions between plants and fungal leaf diseases are also studied in different climate scenarios.
Both the composition and quantity of oilseed rape oil can be changed by abiotic climate stressors like ozone. We want to analyse how climate change effects production and quality of oilseed rape in single- and multifactorial climate scenarios. Therefore, we want to examine, if the oil composition and quantity is changed in climate set ups where ozone, CO2 and temperatureare elevated. The oilseed rapes have been grown in RERAF; Risø DTU’s advanced climate phytotron (http://www.risoe.dtu.dk/en/business_relations/Products_Services/Risk_Assessment/BIO_RERAF/introduction.aspx ). Different genotypes of oilseed rape were cultivated in five different future climate scenarios and the effects of the abiotic climate stressors to oil contents and quality will be compared to effects under ambient conditions
Climate change is a major issue in global debates and its consequences are yet unsure (IPCC report, 2007). Rising temperatures, more extreme precipitation events and longer drought periods are assumed to change the nutrient cycling towards a new equilibrium. For instance, the CO2 concentration in the atmosphere rose due to the frequent usage of fossil fuels (Keeling, 1958) and affected e.g. plant performance (Poorter and Navas, 2003).
As recently reported, the mechanical properties of biopolymers such as polylactide (PLA) can be quickly screened using a micromechanical technique developed at DTU Nanotech. In addition to speed and delivering property values (e.g., modulus) comparable with data from macro-scale testing, the method potentially offers ways to evaluate a material’s response to different conditions of temperature and humidity. The project will extend the work by examining the application and value of this procedure when applied to combinations of biopolymers with organic and inorganic nanofillers (i.e., bionanocomposites), which are of considerable interest for future applications in areas as diverse as food packaging, electronics and medicine. Project activity will take place at both Risø DTU and DTU Nanotech.
Plant materials are primarily made up of three main types of biopolymer: cellulose, lignin and hemicellulose. In the ongoing biofuels research at Risø-DTU hemicelluloses are generated as by-products from bioethanol production. This project involves studies of these compounds as well as commercial hemicelluloses in the design of new composite materials.
The project is designed to investigate new surface treatment technology using polymeric ligands developed at DTU Nanotech to modify the properties of nanofibrillated cellulose. The project is a cooperative activity between Risø DTU, DTU Nanotech, the Paper and Fiber Research Institute of Norway (PFI) and the Norwegian University of Science and Technology
The project will involve the use of advanced computational techniques such as molecular dynamics (MD) simulation.
Projektet sætter fokus på polymere som skal øge effektiviteten og levetiden af organiske solceller. Udover syntesen af denne type polymere vil der også udføres test af polymererne i solceller.
The size of wind turbines has increased significantly over the last 30 years and offshore wind turbines are expected to reach a power output of about 20MW and a rotor diameter of 250m. However, it remains an open question, which structural and aeroelastic design challenges that can be expected for such large blades.
Zephyr/Prediktor is the oldest commercial tool for the short-term prediction of wind power world-wide. It uses WAsP theory to downscale the wind fields from Numerical Weather Prediction input to the actual wind farm site in question. In order to remove the last remaining errors, a Model Output Statistics (MOS) module is used.
Kite types such as the ones known from for instance kite surfing, can be used for generating mechanical power by “winding out” the kite wire while the kite is doing maneuvers (for instance circles directly downwind of the ground attachment) in the air.
