Energy method in solving the problems of stability for a viscoelastic polymer rods

Autor: Yazyev Serdar, Kozelskaya Maria, Strelnikov Grigory, Litvinov Stepan

Publikováno v: MATEC Web of Conferences, Vol 129, p 05010 (2017)

With the energy method in the form of Ritz-Timoshenko solved the stability problem for a polymer rod under axial compression for the clamping-free edge option. The proposed form of loss of stability is chosen as a sum of functions with indeterminate
