i'm trying to make the chocolate evenly spread out on a mould after deposition. mould is conveyed past the cantilever.

metal fatigue is a non trival area of expetise. Generally speaking the fatigue strenght of a metal is based up several factors including the geometry of the section including any stress raisers that may be contained with the section, the number of stress cycles the member is subjected to and the stress range. For any given section and a known number of stress cycles for the life of the section, the fatigue stress of the section can be calculated. If the stress range of the section is less than the fatigue stress calculated using the above variables, the section has theroetic infinite stress life.
Im not sure where you are from, however Australian Standard AS4100 gives a detailed explaination in regard to calculating the fatigue stress of a section. There is also a British Standard based on the "Miner" method this is also excellent. I Hope this helps.

If it doesn't break for some other reason it will probably eventually break because of fatique exacerbated by corrosion - that could be a very long time though and the actual breakage might not pose a human safety risk (depends). How long do you want it to last (longer than the vibrator?)? What are the characteristics of the vibrator ? What is the range of characteristics of the loaded mould? Don't you have concerns about the noise level?

with out any sophestication the answer is yes because the vibration will produce reversable stresses
after how many cycles?
this depends on material, section and the force causing the vibration.

if it's 3mm thick x 20mm wide x 2m long ..r u not gonna brace it ? if so then it wont fail ...........steady vibration will not harm your cantilever ....also try using an intermittent vibration to assist the chocolate to evenly set

I think this question is a little complicated for Yahoo Answers.
