Abstract :
The diffraction of a plane hydroacoustic wave by a short joint of two fluid loaded semi-infinite thin elastic plates is studied. A generalized point model of the joint is suggested. This model reproduces not only the principal order term in the asymptotics of the far field amplitude by the width of the joint, but also the logarithmically smaller corrections
