Non linear Buckling with FEM approach

Buckling analysis assesses the stability characteristics of a structure. An accurate solution to a buckling problem requires more efforts than just following a numerical procedure, there are a number of factors to consider before a buckling solution can be accepted … Continue reading

Buckling of an imperfection-sensitive cylindrical shell

Buckling of an imperfection-sensitive cylindrical shell (EXTRACTED FROM ABAQUS GUIDE) This example serves as a guide to performing a postbuckling analysis using Abaqus for an imperfection-sensitive structure. A structure is imperfection sensitive if small changes in an imperfection change the … Continue reading

Linear Buckling Analysis – SOL 105

Theoretical Background Buckling analysis assesses the stability characteristics dictating the integrity limit of a structure. Let us start with a linear equation of motion for a preloaded structure: where M,C, K and  Kd are mass, viscous damping, material and differential stiffness … Continue reading
