eng	Eigenfrequencies of Pseudo 3D Thick-Walled Composite Arches	In this work laminatedarches are solved under the condition that anisotropic layers are consider and the generalized plane strain state is assumed. In the frame of this assumption it is also supposed the arch is long enough to assume that the dependence of radial and hoop displacements on the axial coordinate is fairly negligible. Mathematical apparatus is fully discussed and formulas needed for programming on computers are derived. The focus here is concentrated on the problem of impact load, which can be simplified by developing the time coordinate into the Fourier series.	dynamical response;cylindrical laminated arches;anisotropic layers;impact load;semi-analytic solution;eigenfrequencies
