On dynamic stability of beam in two statements
Journal Title: Հայաստանի գիտությունների ազգային ակադեմիայի տեղեկագիր․ Մեխանիկա - Year 2009, Vol 62, Issue 2
Abstract
The stability of beam in two cases when on one edge of it the force or displecement in form of periodical function is investigated. The equation of longitudinal vibrations is solved exactly and solution of stability equation is reduced to Couchy problem for infinite system. It is shown that in case of main parametric resonance one can acrount that compression force is constant along length of beam. Also is considered problem of stability when applied displecement is in impact form.
