WP 1 Project Coordination

with the financial administration and technical management of the project.
WP 2 Advanced Tools for Simulation & Experimentation
The subject of this work package is the assessment and optimization of advanced tools
for simulation of dynamic events and for experiments involving dynamic events
affecting composite materials and components in vehicles.
objectives of WP2 are associated with harmonizing the common
characteristics of both simulation and experiments, identifying quantitative
damage parameters for composites structures, and with optimizing the tools for both simulation and
The limitations of numerical
models and experiments are usually different and can lead to a divergence of
the boundary conditions which in turn can
make integration of the results difficult or impossible. This work will include the use of
Quantifying damage in composite vehicle components supports the assessment of structural integrity and in particular residual
life. A high level of confidence can be achieved through good quality validation.
The outcome will enable a realistic case
study on Experimental Validation, and will
result in the generation of a draft standard guide for optical deformation measurements
in dynamic events
WP 3 Dynamic CalibrationThis work package is concerned with the Development of Reference Materials for dynamic events. The aim is to produce a unified set of reference materials for cyclic, transient and non-linear events.
The rational decision making model is applied and leads the participants through definition of essential and desirable attributes, identification of alternative solutions, quantitative evaluation of alternatives against attributes, and selection of the preferred solution.
Specification of the reference materials will be in a format suitable for incorporation in a draft standard or ISO Technology Trend Assessment.
WP 4 Experimental ValidationThis work package is concerned with generating a generalised methodology for integrating data from experiments and simulations. Current practice tends to focus on identifying hot-spots in the data and checking that the two approaches agree in these critical zones. This highly localised approach neglects the majority of the data generated by optical techniques and carries with it the risk that critical regions will be missed all together. Work will consider full-field comparison methods that will lead to the establishment of confidence levels for the numerical models. These methods and the reference materials developed in WP3 will be evaluated through case studies using industrial components manufactured from composite and subjected to a dynamic event.
Whilst the impact in homogeneous panels is a relatively straightforward task, the simulation of impact and subsequent development of damage in a composite panel is probably at the leading edge of current knowledge. The simulation of such events in curved or a three-dimensional composite panel is just beyond current capabilities. The aim will be to optimise the simulation methodologies so that curved panels can be reliably modelled during dynamic events. Experimentation and simulations will be performed on the components and the resultant data integrated to generate a validation.
Finally, a set of guidelines based on the unified methodology for experimental validation will be made available to the industry in a standard guide.
WP 5 Dissemination Activity
This work package is concerned with liaison with technical and standards organisations (VAMAS
TWA26 on optical
techniques of strain measurement.; NAFEMS on FE Analyses; CEN
dissemination of the unified methodologies
and reference materials to the EU industrial base is important since significant
benefits can accrue from their informal adoption.
