Transient stress Analysis

[sriramsheval]

Hi,

I did a Static analysis of one component, with a same boundary condition and load I tried the Transient stress Analysis.

But the result were so irrelevant. I gave a curve input as Linear load curve.

Run the Analysis and got following outputs ... please help me to know what mistake i have made

I even tried giving values to ALPHA and BETA, as .01 .. still i get the same result as shown above

Hi sriramsheval,

Your details are a little sketchy, so it is hard to know what is wrong. But one difference between static analysis and transient analysis is inertia; that is, the mass. So my guess is that your mass density is wrong. Run the "Analysis > Analysis > Weight and Center of Gravity" and see if the weight is correct.

If the weight is okay, and the other material properties are okay, then my guess is the load curve and the applied load are creating more force that you anticipate.

If you cannot find the problem, I suggest that you attach an archive of your model. See "Create, Post, or Provide an Archive of your model".

Hi John,

Thanks for your help, now it works. After I add density.

thanks
