RE: Load
RE: Load
Otherwise, you should be able to come up with an order-of-magnitude type value of stresses due to the weight of the object being analyzed.
Consider then, what the uncertainty is on your applied loadings. For example, if your applied loads are assumed, or based on some probabilistic analysis, they aren't going to be accurate to 8 decimal places. If you get, say, 10,000 PSI stress based on a load that could actually vary +/-25% or more, and estimate that gravity loading gives you 100 PSI, there really isn't much point in calculating gravity loading.

RE: Load
as ericZhao said, more details otherwise we'll all answer the question from our own perspective (like maybe in the zero g environment of space).
generally, if the structure's weight is small compared to other applied loads, and if the inertial accelerations are small.
