Deteksi Kerusakan Plat Dengan Menggunakan Sinyal Suara
ABSTRACK Structural Health Monitoring (SHM) is a process of identifying damage by Nondestructive Evaluation (NDE). The method can be done by non-contact method. In this study a non-contact method was proposed to monitor the spesimen by ultilizing the sound signal as an excitation. This method has advantage becauseit is not costly toset-up testing.Excitation is given to spesimen by the loud…
