Buckling of Stiffened Thin-Walled Cylindrical Shells under Axial Compression with Symmetrical Imperfections
This study aimed to investigate the effects of stiffeners on buckling of thin cylindrical shells under uniform axial compression. To this end, more than 300 finite element models of stiffened cylindrical shells were prepared. The variables considered are shell thickness, number, dimension and the location of the vertical and horizontal stiffeners as well as circular symmetrical imperfections. R...
متن کاملDynamic buckling of thin cylindrical shells under axial impact
The dynamic buckling of thin isotropic thermoviscoplastic cylindrical shells compressed with a uniform axial velocity prescribed at the end faces is investigated analytically and numerically. In the first part of the paper, the stressed/deformed state of a shell is assumed to have buckled if infinitesimal perturbations superimposed upon it grow. Cubic algebraic equations are derived for both th...
متن کاملBuckling of cracked cylindrical thin shells under combined internal pressure and axial compression
Linear eigenvalue analysis of cracked cylindrical shells under combined internal pressure and axial compression is carried out to study the effect of crack type, size and orientation on the buckling behavior of cylindrical thin shells. Two types of crack are considered; through crack and thumbnail crack. Our calculations indicate that depending on the crack type, length, orientation and the int...
متن کاملOn the buckling of cracked composite cylindrical shells under axial compression
Potential sensitivity of the buckling behavior of cracked composite cylindrical shells to service life cracking is explored by carrying out linear buckling analysis. Computational models of cracked composite cylindrical shells are developed by exploiting a special meshing scheme in which the element size is reduced incrementally from the element size employed in the uncracked region by approach...
