Abstract
This paper detects, through numerical simulations, the stress in structures using lamb waves. The finite element model of steel plate was developed using the commercial finite element programs ABAQUS and ANSYS. Dynamic models were run for Lamb wave propagation in steel plate under the effect of different compressive and tensile stresses. The simulations have revealed that with the variation of stress there is no effect of time of flight. In the case of compressive stress, it's found that the amplitude of received wave is increased slightly with increasing of compressive stress. In otherwise of tensile stress, the amplitude of received wave is also decreased slightly with increasing of tensile stress.
