ANALYSIS OF MATERIALS FAILURE BY USING COMPRESSION LOAD CELL

MECHANICAL ENGINEERING

To develop a system which provides information about damages and deformation of an onboard aircraft using compression load cell sensor array embedded in glass fiber reinforced polymer (GFRP) based composite materials. Interest in, and utilization of, FRPs in engineering products has steadily grown over the last three decades. Their high strength-to-weight ratios and rot and corrosion resistances are advantages for an increasing number of diverse applications from armory through to yachting and land transportation. Composite materials have been increasingly used in automotive engineering, aerospace development, marine technology, electronic devices, and construction industries. General purposed commercial finite element code was employed to develop the computational model. Glass fiber reinforced composite, one of the commonly used structural composites, was chosen for the test material. Computational model was constructed using 3- D finite elements. For comparison purpose, compression load test was carried out the load and the specimen size as close as possible to those used in computational model. Both computational and experimental results are found to be in good agreement in terms of damage size. A simple setup to predetermine the fracture load is fabricated and a test for load condition of 4kg's chosen to test the setup and a successful attempt is made to show the capabilities of the setup.
