So far the authors have presented a technique for detection of breathing cracks in a beam. The presented technique uses the incremental transfer matrix method. In some cases, due to the problem in treatment of the opening and closing condition for a breathing crack, the incremental transfer matrix method can not analyse a cracked beam. In this report, a detection technique which uses the finite element method based on the mixed variational principle instead of the incremental transfer matrix method is proposed. In the proposed technique the opening and closing condition for a breathing crack can be treated without any problems The applicability of the proposed technique is presented via numerical simulation.
