Damage assessment of laminated composite beam structures using damage locating vector (DLV) method

Vo-Duy, T. / Nguyen-Minh, N. / Dang-Trung, H. / Tran-Viet, A. / Nguyen-Thoi, T.

Abstract In this paper, the damage locating vector (DLV) method using normalized cumulative energy (nce) is employed to locate multiple damage sites in laminated composite beam structures. Numerical simulations of two laminated composite beams are employed to investigate several damage scenarios in which the degradation of elements is modeled by the reduction in the longitudinal Young’s modulus and transverse Young’s modulus of beam layers. The results show that the DLV method gives good performance for this kind of structure.
