Theoretical investigation of the deformed graphene nanostructures

 The results of the theoretical investigations of properties of the deformed graphene structures are presented in this work. We investigated mechanical properties of the bi-layer graphene structures by means of the molecular dynamics method. To evaluate mechanical properties of graphene we applied a compression load to graphene. As a result of the investigations it was found that graphene became a wave-like with the increase of the compression. The number of half-wave, generated on the graphene surface depends on the size of graphene. 

Oscillations of shallow shells at abrupt influence of thermal flow

On the basis of the closed integrals of the initial and boundary problems for incoherent thermoelastisity of shallow shells the quantitative analysis of influence of the geometrical parameters on the oscillations of constant rotation and cylindrical shells, which are conditioned by the thermal shock to outbound surface of shallow shell are carried out.
