ST7-1.10.10.6 Linear Buckling Analysis
In order to gain an appreciation for the process of performing a linear buckling analysis and to be able to interpret the results, it is important to keep in mind the fundamental question that the linear buckling solver answers, namely: The linear buckling problem can be represented by the following relationship:
which can be rearranged as the following eigenvalue problem:
where
is the global stiffness matrix of the structure;
is the geometric stiffness matrix, which depends...
