Biaxial testing of fibre reinforced composite laminates
Abstract
Advanced composite material systems are increasingly used in virtually every industrial branch. The structural components manufactured from these composite material systems are usually subjected to complex loading that leads to multiaxial stress and strain fields at critical surface locations. The current practice of using solely uniaxial test data to validate proposed material models is simply inadequate. In order to test closer to reality a biaxial test bench using four servo-hydraulic actuators with four load cells was developed. Beside the development of the test facility, a mixed numerical/experimental method was developed to determine the in plane stiffness parameters from testing a single cruciform test specimen. To obtain the strength data an optimised geometry for the cruciform type specimen was designed. For the optimisation procedure a full 3D finite element model was used. The numerical results were validated with strain gage, Digital Image Correlation (DIC) and Electronic Speckle Pattern Interferometry (ESPI) data.
