Theoretical and experimental evaluations of strain field modification induced by flaws in loaded composite structures

Project description

Investigating strain field modification caused by flaws in subcomponents and structures

The distribution of strains through a region of a body is referred to as a strain field. Damage or defects to loaded composite structures cause their strain field to be modified. The EU-funded MODIFLAW project therefore aims to develop, apply and validate numerical models of strain field modification that is caused by the presence of flaws of different forms and sizes. It further aims to define virtual morphology for diagnostic indications provided by structural health monitoring (SHM) data and software on damaged subcomponents and structures. The project will advance research on novel inexpensive and low-weight processes and SHM technologies.

Objective

Theoretical and experimental evaluations of strain field modification induced by flaws in loaded composite structures:
The main objectives of the project is to develop, apply and validate numerical models of the strain field modification induced by the presence of flaws with different kind of morphology and size and to define virtual morphology for diagnostic indications provided by the Structural Health Monitoring (SHM) data and software on damaged representative sub-components and structures.
The project results will contribute also to innovative low cost and low weight processes and SHM technologies which will be integrated into the Outer Wing Box on ground demonstrator and into the Fuselage structural demonstrator with the objective to obtain: structural weight reduction, manufacturing and assembling recurring cost reduction, maintenance improvement and implementation of new eco-compatible materials and processes.
