SIMULATION: AMFFE
The general objective of the project AMFE is to analyse and model the behaviour in fatigue of elastomers by integrating the already existing models of behaviour and the ones that will be developed throughout the project in a computer application for the forecast of the long term behaviour of these kind of materials using a methodology based on the use of the Finite Elements Method (FEM).
So as to achieve the general objectives of the project, we propose the following specific objectives which moreover, seek to solve the shortages previously mentioned:
- Analyse through experimental tests the mechanical behaviour of the elastomers of interest and determine the constitutive models which represent all the phenomena and mechanisms involved. Implement the defined models in a finite elements calculation program. Practically no author models properly the static behaviour of elastomers and this is the most important information for the correct determination of the behaviour in fatigue. The use of the finite elements method for reproducing the mechanical phenomena characteristic of the static behaviour of elastomers is not widespread either.
- Analysis through experimental tests for the determination of the models which represent the phenomena characteristic of the behaviour in fatigue of elatomers. As happens in the static case, the behaviour in fatigue of elatomers is characterised by numerous phenomena which have to be studied and integrated in one single model.
- Implement the models of fatigue of elastomers in a computer application. This application will integrate the already existing models and the ones developed throughout the project. Moreover, this application together with the programs of finit elements will make it possible to know the long-term behaviour of elastomers according to their mechanical requirements. The achievement of these three partial objectives will mean the achievement of the general objective of the project. With all this, we will have generated and integrated the necessary knowledge for making possible the proper development of elastomeric components with requirements that can vary in time, in other words, in fatigue.
