FUNDAMENTAL MODELS OF STRUCTURAL STABILITY
Journal Title: UNKNOWN - Year 2017, Vol 32, Issue 2
Abstract
In this paper, basic structural stability phenomena are described. After some general comments about stability in the field of civil engineering, four elementary sources of nonlinearity are mentioned: of equilibrium equations, strain (geometry) relations, material (stress-strain) law, force and displacement boundary conditions. Four fundamental stability models are analysed, both ideal (perfect) and with geometric imperfection. Besides geometrically exact theory, initial post-buckling behavior and linearization are briefly sketched. This paper is concluded with comments about the influence of plasticity.

PRIMJENA PELETA U LABORATORIJSKIM ISPITIVANJIMA MEĐUDJELOVANJA INHIBIRANE ISPLAKE I ŠEJLA
Nestabilnost kanala bušotine predstavlja ozbiljan problem koji se najčešće javlja tijekom bušenja kroz šejl. Uzrok nestabilnosti šejla proizlazi iz njegovog mineraloškog sastava (osobito udjela minerala glina) i njegovih...
