Hello all,<\/p>\n

I have watched the video lecture in Random vibration using ANSYS, <\/p>\n

Video Lecture: <\/p>\n

\/courses\/index.php\/courses\/random-vibration-analysis\/lessons\/how-to-correctly-interpret-psd-results-lesson-3\/<\/p>\n

In that lecture at 13:41 minutes, the lecturer shows that the equivalent stress plot in GUI is 94.454 MPa and for 3 – sigma it is 283.35 MPa, Here I have doubts. Supposing I have a material yield strength of 250 MPa, can we say that the table will fail because it exceeds the yield strength of the material?<\/p>\n

Otherwise, I should see the RMS stress graph values in the (detail window) response PSD graph after extracting them at the particular location.<\/p>\n

(An example is shown in the video itself for displacement in X at 14:35 minutes. ) Likewise Should I see the equivalent stress value, compare it to yield strength, and decide whether the design is safe or not?<\/p>\n
