Hi all
Im a beginner and trying to modelling a flat plates in the Roark .
i have a plate 10 in x 3 in all edges all edge fixed and a uniform pressure of 100 psi over all the plate. im using the Ls pre-post for now and studying Ls Dyna Implicit Analys.
For modelling my load condition after the mesh generation, have i to load my shells with a load curve (Abscissa time , Ordinate pressure)?
Best Regards

so i guess one way to answer (not knowing LS Dyna, usually used for dynamic analysis, another clue i thnk 40818 picked up on) is "no" you don't need to apply a time varying load. guessing that LS Dyna wants time-dependent loads, i'd suggest that either you use a different code (one grounded in statics) for this (though i figure you've thought of this already and decided that the only code accessable to you is LS Dyna) or put in a constant load.
good luck

Here is an excellent site which has many examples. This should get you familiar with the basics:
