PERTURBATION APPROACH TO ELASTIC POST-BUCKLING ANALYSIS

This paper aims to show that effective and reliable computer codes can be obtained by a suitable finite element implementation of the Koiter's perturbation method. However, careful attention has to be paid to all the implementation details in order to avoid kinematical inconsitencies that can s...

Description
Summary:This paper aims to show that effective and reliable computer codes can be obtained by a suitable finite element implementation of the Koiter's perturbation method. However, careful attention has to be paid to all the implementation details in order to avoid kinematical inconsitencies that can strongly affect the results.
