摘要：

We study natural vibrations of a cantilever nonclosed orthotropic cylindrical shell with an arbitrary plane directrix. We assume that the shell is hinged on two generators and its bending rigidity is zero ( a membrane shell). We find the dispersion and characteristic equations for the characteristics of natural frequencies and damping ratios of the corresponding modal vibrations. Specific computations are performed for shells with directrix being a parabola and with various values of the curvature and length of the generator.
