WISMOS stands for Wireless/ Integrated Strain Monitoring and Simulation System
 

This project addresses the development and real time test validation of an integrated hardware and software environment that will be able to measure real-time  in-situ strain and deformation fields using a state-of-the-art wireless sensor system to enhance structural durability and damage tolerance (D&DT), reliability via real-time structural health monitoring (SHM) for sensorized aerospace structures. The tool will be a vital added extension of existing suite of structural health monitoring (SHM) and diagnostic prognostic system (DPS). The goal of the extended SHM-DPS is to apply a multi-scale nonlinear physics-based finite element analyses (FEA) to the “as-is” structural configuration to determine multi-site damage evolution, residual strength, remaining service life, and future inspection intervals and procedures. Information from a distributed system of wireless sensors will be used to determine the “as-is’ state of the structure versus the “as-designed” target.  Software enhancements will incorporate information from a sensor network system that is distributed over an aerospace structural component. As case study DPS application a realistic composite stiffened panel representative of fuselage/wing components will be selected.  Two stiffened panels will be manufactured and instrumented; a) embedded internally between composite layers, and b) surface mounted with wireless sensors; the second of which with an optimized sensor network. The panels will be tested in compression following low-velocity impact. The sensor system output will be routed and integrated with a finite element analysis (FEA) tool to determine the panel’s, multi-site damage locations, and associated failure mechanisms, residual strength, remaining service life, and future inspection interval.  The FEA will utilize the web/internet based GENOA progressive failure analysis commercial software suite, durability and damage tolerance (D&DT), and reliability software capable of evaluating both metallic and advanced composite structural panels under service loading conditions.  The project will utilize a building block validation strategy, and real-time structural health monitoring system.  
This is a project under the umbrella of Clean Sky, EcoDesign ITD.

CleanSky Project: WISMOS (Wireless Integrated Strain Monitoring and Simulation System), February 2010 -July 2012

Description: This project addresses the development and real-time test validation of an integrated hardware and software environment, that will be able to measure real-time in-situ strain and deformation fields in a structure using a state-of-the-art wireless sensor system. The tool will be a vital added extension of existing suite of structural health monitoring (SHM) and diagnostic prognostic system (DPS). The goal of the extended SHM-DPS is to apply a multi-scale nonlinear physics-based finite element analyses (FEA) to the “as-is” structural configuration to determine multi-site damage evolution, residual strength, remaining service life, and future inspection intervals and procedures.  As case study for DPS application, two realistic composite stiffened panel, representative of fuselage/wing components, were manufactured, instrumented and tested in compression following low-velocity impact. The developed environment is applicable to enhance structural durability, damage tolerance (D&DT) and reliability via real-time structural health monitoring (SHM) in sensorized aerospace structures.
