I'm looking into finding the max stress of a part within a Linear Dynamic study. The part is an angle bracket with a gusset. One side is fixed with the other carrying a 10kg load at its end. The part under goes a 1g excitation load in the vertical direction.
When the analysis is run, a stress plot is created. The plot demonstrates a max stress value. However, when I use the probe at this max stress location, the response at its natural frequencies appear much higher than the initial value given at the stress plot.
Can anyone help me understand this - I need to find the max stress in the part at all frequencies, not just the one found on the stress plot or the max at any point selected?
