Non-Linear Buckling Analysis of a Process Column

Posted on 8:37 pm

A non-linear Finite Element Analysis (FEA) was performed to determine the possibility of a local and/or global structural buckling instability in a process column under a partial vacuum of -1.5 psig. A local area, with various thin sections, was investigated for possible failure during the operation of the column. The resulting stress intensities, strain, and deformation were analyzed using the general intent of ASME Section VIII, Division 2 code.
