TL;DR: In this paper, a nonlocal plate model was developed to study the vibrational characteristics of multi-layered graphene sheets with different boundary conditions embedded in an elastic medium, and the results obtained from the present numerical solution have been compared with the existing data from the literature and good agreement has been found.

TL;DR: In this article, the energy absorption and collapse mode of circumferentially grooved thick-walled tubes are scrutinized analytically and experimentally under dynamic loading condition and the effect of strain rate is incorporated into the equations by implementing the Cowper-Symonds constitutive equation.

TL;DR: The experimental investigations reaffirm the theoretical studies and reveal that the developed inexact-finite similitude theory can practically be used for predicting full-scale behaviour by conducting experimental tests on trial models of different sizes and even different materials.

TL;DR: In this paper, the von Mises yield criterion is used for the elastic-plastic cylindrical shell made of linear strain hardening material in order to derive the constitutive relations between stress and strain increments.

TL;DR: In this article, the effect of thickness distribution on shortening, energy absorption, axial force and buckling shape of tubes is investigated experimentally and numerically by using a striking mass to impact tubes.
