Its principle is : a laminated structure ( beam or plate ) with delamination consists of undelaminated region and delaminted region which can be divided to upper and lower parts. when a low - amplitude and high - frequency excitation has the frequency close to some part ' s natural frequency, this part will resonate and certain amount of mechanical energy will convert to heat so that the delaminated region ' s temperature exceeds greatly that of the undelaminated region. therefore the delamination can be located by means of infrared thermograph
其原理是具有脫層的層合材料構件（梁或板）包含脫層區域及未脫層區域，脫層區域分為上下兩部分，若對層合材料構件施加小振幅、高頻率的振動激勵，當激勵頻率恰好接近其中一部分的固有頻率時，該部分就會產生共振響應，部分機械能將轉化為熱能，使脫層區域的溫度遠高於未脫層區域，藉助紅外熱像儀即可顯示出脫層的位置。And gave priority to the eular - bernonulli beam model, the simply and convenient analytical resolution for the response of the pipelines under dynamical traffic loads through the impulse function and the congruence method of the vibration form and so on. during the analysis of the chanmical results of the pipelines, the randomicity of the output of the pipelines response was taken into accout. so the stochastic process method was applied to describe the probability characters of the pipelines response, which made the results truer, more veracious
