چکیده
In this paper, the fuzzy scattering problem with semicircular depressions on boundary of a band-shaped elastic plate steady SH guided wave incident is studied and an analytical solution given. First, constructed by expansion method, then scattered satisfying free condition stress strip domain cumulative mirror method. Finally, definite equation obtained based fact that shear at edge semi-circular recessed hole zero. ambiguity number waves width bands taken into account. order to avoid irreversibility interval algorithm difficulty solving non-linear equations, membership function quantity segmented make degree correspond respectively. A deterministic translates piecewise processing. Two numerical examples are given examine changes in response different numbers thicknesses dynamic concentration factor hoop collapse limit.

Numerical Modeling Of Obliquely Incident Guided Wave Scattering By A Crack In A Laminated Composite Plate
In this paper, we consider scattering by a guided wave incident obliquely on a surface breaking crack in a laminated composite plate, with a view to ultrasonic nondestructive assessment of cracks. The solution to this problem is the first step towards analyzing the general three-dimensional scattering problem. The method used for modeling is a hybrid method which combines finite element method ...

متن کاملWater-wave scattering and energy dissipation by a floating porous elastic plate in three dimensions
An eigenfunction-matching method is developed for the problem of linear water-wave scattering by a circular floating porous elastic plate, and a coupled boundary-element and finiteelement method is developed for the problem in which the plate is of arbitrary shape. The methods are shown to produce the same solutions for a circular plate, and their convergence properties are established. The imp...
