Abstract |
|
The dynamic stress concentration factor (DSCF) around a nanosized elliptic cavity is considered by adopting the conformal mapping method. The generalized Young–Laplace equation is used in the solution of stress boundary conditions on the interface. The DSCF along the interface of the elliptical cavity is numerically evaluated. With the changing of surface effects, the incident wave’s frequency and propagating angle, the degrees of dynamic stress concentration become more obvious on the interface. Our results can aid in analyzing the mechanical properties of defective nanocomposites. The proposed method can better solve the scattering problem of variable curvature on elastic substrates. |
