✦ Synopsis

The post buckling behavior of imperfect columns made of linear viscoelastic materials is investigated within the elastica theory, taking into account the eect of the strain in the neutral axis. The material is modeled according to the Boltzmann superposition linear viscoelasticity. A solution is developed in order to calculate the growth in time of the total deΒ―ection, and to establish the importance of the column compressibility while analyzing its postbuckling behavior.

The stability problem associated with an Euler-Bernouli beam made of an arbitrary linear viscoelastic material is formulated. The three parameter and the Kelvin-Voigt models are analyzed in the presence of constant as well as periodic loads. The application of a finite time stability concept is show
