negative eigenvalue for linear buckling
negative eigenvalue for linear buckling
(OP)
Does a negative eigenvalue in linear buckling with a magnitude greater than one signify that the direction of the load produces such a safety factor? Or does it mean that the matrix solver could not converge? Help please.

Try with a simple column and load it with both tension and compression. The tension case should giva negative eigenvalue and the compression should give positive value. Provided that you use the same load you should get the same absolute value.
