Buckling Of Cones With Imperfect Length Subjected To Axial Compression

The paper considers the effect of imperfect length on the buckling behavior of mild steel truncated cone subjected to axial compression. The contact interaction problem between the rigid plate and the cone was successfully benchmarked against experimental data on axially compressed cone with imperfe...
