On Static Stability of Nonlinearly Elastic Euler's Columns Obeying the Modified Ludwick's Law
|Published in:||International Journal of Structural Stability and Dynamics, December 2012, n. 6, v. 12|
It is illustrated in this paper that a nonlinearly elastic column, depending upon the values of different material parameters involved, exhibits several stability characteristics and types of buckling which are generally observed separately in distinctively different structural systems. By introducing finite disturbances it is shown that the column may buckle well before the bifurcation buckling load is reached. The proposed approach can be useful in engineering practice since it can be utilized to study the stability of uniaxial structural elements made from rubber or any other material which obeys the modified Ludwick's constitutive model.
