Dynamic behaviors of cylindrical shells with geometric imperfection [PDF]

MATEC Web of Conferences, 2019
For finding out the relationship between vibrational modes and geometric imperfections, the dynamic behavior of cylindrical shells with a local imperfection is analyzed by using numerical simulation of finite element method in this paper. The results show that there are some differences in vibrational modes between cylindrical shells with and without ...
