PREDICTION OF THE MECHANICAL BEHAVIOR OF COMPOSITE STRUCTURES BASED ON MATHEMATICAL MODELING AND TECHNOLOGIES OF SMART MATERIALS

摘要

The problem of prediction of the mechanical behavior of composite structures is achieved both based on mathematical modeling techniques and different experimental methods, providing the measurement of the required mechanical properties. In this work, prediction of the mechanical behavior of composite structures is based on the joint use of methods of mathematical modeling and results of strain measurements via embedded into material fiberoptic strain sensors with Bragg gratings. Strain measurement results must at any given time confirm the accuracy of the simulation results. They are also used to refine the model parameters that are used for the calculation at the subsequent time steps.
