Composite Materials

Simulation of mechanical response

  • The plastic model was implemented with combination with asymmetric mechanical properties (modulus, strength) and failure criterion.
  • The proposed FE model well-simulated the asymmetric nonlinear behavior of different types of composites.

Prediction of fatigue properties

  • An accelerated testing method of the fatigue properties based on the time-temperature superposition principle was proposed.
  • New predictive model of S-N curve at various stress ratio and CLD of FRPs was suggested.
