description: The topic of the final qualification work: Â«Nonlinear dynamics of Nano systems made of two-dimensional materials under laser thermo-optical influences". This thesis focuses on the nonlinear dynamics of nanosystems made from two-dimensional materials under laser thermo-optical influences. The study is dedicated to understanding resonant processes during longitudinal and transverse vibrations: 1. Construction of continuum models of moving elements of two-dimensional nanosystems. 2. Construction of compact analytical models and their qualitative study using asymptotic methods of nonlinear mechanics. 3. Study of such effects that represent scientific novelty and technical significance, such as giant parametric amplification of oscillations, control of the noise characteristics of the sensor, the creation of the so-called. phonon frequency combs, the use of internal resonances when designing the operating mode of the device. In the course of the work, the quality factor properties of resonator oscillations were studied. A comparison of analytical and numerical calculations of the quality factor is given using the example of resonators of two types of media depending on their parameters. Numerical studies were carried out using the Ansys Apdl finite element analysis program. Vibration graphs were obtained for varying various geometric parameters, taking into account longitudinal and transverse vibration.
