Stability analysis of surfaces (esas.14)

esas.14

Stability calculations are used to obtain an insight into the buckling mechanisms of a structure, to calculate the buckling length of a member for use in the Steel Code Check, to verify if 2nd Order calculations are required,…

This module helps to determine the global critical buckling modes and buckling loads of structures including surface elements (plates and shells).

Highlights |
---|

User input of number of buckling modes to be calculated. |

The results include buckling factors (ratio between the critical buckling load and the applied load). |

Deformed shape can be displayed graphically for each calculated buckling mode. |

The critical buckling mode can be imported in the geometric non-linear calculation as an initial deformation (in combination with geometrical non linear module). |

##### Example of the usage of linear stability calculation for arch bridge modelled with shell elements.
