Damage Identification of Functionally Graded Bernoulli-Euler Beam Based on the Modal Strain Energy Method

Abstract:

An algorithm based on modal strain energy method was proposed to identify the existence, the location and the extent of damage for a functionally graded materials (FGMs) Bernoulli-Euler beam. ABAQUS standard finite element program was used for the dynamic analysis of the FGMs Bernoulli-Euler beam. The damage indicator for the damage identification of the FGMs Bernoulli-Euler beam was developed by way of modal strain energy method. A numerical example was given to demonstrate the effectiveness of the proposed algorithm. Numerical results show that the proposed algorithm is effective in identifying the damage for the FGMs Bernoulli-Euler beam.
