Modified Spline Collocation Method in the Problems of Thin Rectangular Viscoelastic Plate Vibration

Authors: Nedorezov P. F., Romakina О. М., Safonov R. A.

Numerical method for evaluation of critical frequencies during steadystate bending vibrations of viscoelastic plate is presented. The solution is based on applying modified spline collocation method for lowering the problem’s dimension and numerical solving of the obtained problem via discrete orthogonalization method. The application of this approach with different boundary conditions is examined in detail.

Bend of Composite Anisotropic Slab Under Normal Loading

Authors: Kopnina V. I., Krylova E. Y.

In this contribution, deflected mode of a thin slab under bending is investigated by the Lehnicky method of complex potential. The slab is composed of two elliptical rings; they are embedded in each other without tension. Material of the rings is anisotropic and different.
