    Pipe lift off in dynamic analysis

    Thank you Saplanti. This is a good procedure to infer where the lift may be, however modal analysis does not provide magnitude or the one provided is not real. Then we would need an actual magnitude of displacement. I suggest to compare the static sustained load case load at each restrain with...

    Pipe lift off in dynamic analysis

    Dear all, This topic may have been already replied somewhere, but I cannot find it. Since dynamic analysis is strictly linear, and the results provided for ABS combination are always positive, how can we perform a lift off check in such type of analysis? Very grateful for your replies. Best...

    Stress analysis of flexible vacuum insulated pipe.

    Hi all, I have to carry out a stress analysis for a cryogenic network made of flexible vacuum insulated pipes. The structural integrity under thermal and seismic loading has to be checked. Normally these kind of analysis are performed following a piping code that gives acceptance criteria and...
