Abstract
Protein structures, that form intermediate filaments (IFs) was first found by an experiment known as the computerized analysis of amino acid sequence of a human epidermal keratin derived from cloned cDNAs. This study is made by the application of Euler beam theory. The buckling of intermediate filaments is studied keeping the nonlocal effects under consideration. It is observed that the nonlocal parameter has a great impact on the dynamics of intermediate filaments. The buckling behavior of intermediate filaments is investigated with different four conditions like as simply supported, clamped, cantilever and propped cantilever beam. Also the effect of critical bucking force is seen for different strengths of nonlocal parameter as 1,2,3,4.
