Dynamic buckling of thin cylindrical shells under axial impact
The dynamic buckling of thin isotropic thermoviscoplastic cylindrical shells compressed with a uniform axial velocity prescribed at the end faces is investigated analytically and numerically. In the first part of the paper, the stressed/deformed state of a shell is assumed to have buckled if infinitesimal perturbations superimposed upon it grow. Cubic algebraic equations are derived for both th...
متن کاملBuckling of Spherical Shells Revisited
A study is presented of the post-buckling behavior and imperfection-sensitivity of complete spherical shells subject to uniform external pressure. The study builds on and extends the major contribution to spherical shell buckling by W.T. Koiter in the 1960’s. Numerical results are presented for the axisymmetric large deflection behavior of perfect spheres followed by an extensive analysis of th...
متن کاملBuckling of Shells—pitfall for Designers
PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...
متن کاملBuckling Analysis of Concrete Spherical Shells
In some simple two-dimensional structures it is sufficient to determine only the lowest value of the load at which buckling commences. However, in the case of shells, it may be also necessary to investigate the postbuckling behavior because it has an important bearing on the magnitude of the failure load. The importance of the postbuckling behavior, which the small deflection theory of buckling...
متن کاملBuckling and Postbuckling Analysis of Shells under Quasi-static and Dynamic Loads
With dynamic loading like landing impact a distinction should be made between relatively short and long, quasistatic loading durations, and loadings the durations of which are in the order of the longest lateral period (lowest eigenfrequency) of the structure. A particular problem is to be expected under the later loadings where the interaction of loading dynamics with the dynamics of the buckl...
