Postdoc in computational modelling of chemical recycling of composites, Denmark

Recyclability of composite blades is an important requirement for future wind turbines. There exist a number of solutions for the recycling of wind turbine blades. How to compare and optimize various composite recycling technologies? How to ensure efficiency of technology and quality of products? This will be a task for new postdoc at DTU Wind.

Postdoc position in Denmark, DTU Wind: Computational modelling of life extension and maintenance of wind blades

Postdoctoral position in Computational modelling of life extension and maintenance of composite blades of wind turbines, at DTU Wind.

Wind turbines are decommissioned after 20...25 years of service. However, blades can be potentially exploited for 50 or more years. How to predict and extend the lifetime of wind turbine blades? How to optimize repair of blades, to ensure their extended lifetime?

Abaqus/Python - commands to find nearest node to a given point

I need to write a python comman code to find a node (in a given set), nearest to a given point.
The code now looks as follows:
import sys
import nearestNodeModule
a = mdb.models['FibreModel'].rootAssembly
n1 = a.instances['Fibre0-1'].nodes

How to investigate the thin layer between graphene sheets and surrrounding polymer (epoxy)?


There is an assumption that nanoparticles (e.g., graphene or CNT) change the local properties of polymer (here, epoxy) around them, perturbing the polymer chains. Which (not too expensive) methods exist to explore this assumption experimentally? How can I study the atomistic scale structure of polymer around the graphene sheets, and compare it with rest of polymer?

Micromechanics of hierarchical materials: a brief overview

A short overview of micromechanical models of hierarchical materials (hybrid composites, biomaterials, fractal materials, etc.) is given. Several examples of the modeling of strength and damage in hierarchical materials are summarized, among them, 3D FE model of hybrid composites with nanoengineered matrix, fiber bundle model of UD composites with hierarchically clustered fibers and 3D multilevel model of wood considered as a gradient, cellular material with layered composite cell walls.

Fatigue of multiscale composites with secondary nanoplatelet reinforcement: 3D computational analysis

3D numerical simulations of fatigue damage of multiscale fiber reinforced polymer composites with secondary nanoclay´reinforcement are carried out. Macro–micro FE models of the multiscale composites are generated automatically using Python based software. The effect of the nanoclay reinforcement (localized in the fiber/matrix interface (fiber sizing) and distributed throughout the matrix) on the crack path, damage mechanisms and fatigue behavior is investigated in numerical experiments.

Hybrid and hierarchical nanoreinforced polymer composites

Hybrid and hierarchical polymer composites represent a promising group of materials for engineering applications. In this paper, computational studies of the strength and damage resistance of hybrid and hierarchical composites are reviewed. The reserves of the composite improvement are explored by using computational micromechanical models. It is shown that while glass/carbon fibers hybrid composites

Graphene reinforced polymer composites: 3D micromechanical modelling, damage and fracture

3D computational model of graphene reinforced polymer composites is developed and applied to the analysis of damage and fracture mechanisms in the composites. The graphene/polymer interface properties are determined using the inverse modeling approach. The effect of composite structure, in particular, of the aspect ratio, shape, clustering, orientation and volume fraction of graphene platelets on the
mechanical behavior and damage mechanisms of nanocomposites are studied in computational experiments.
