Non linear Transient Analysis

Karthic_22061

Hi ,

I tried a simple case for nonlinear transient in Optistruct and its considering the dynamic effects as told in help

I still wonder how come a nonlinear transient analysis takes dynamics(inertia / momentum) into consideration but the simple direct transient does not ?

If non-linearity(Contact/ Geometric/ material ) is the difference between those two cases, how do they vary dynamically

Please help me know the reason for it.

Thank you

Hi Karthik,

I will try to find relevant information for you.

Hi Prakash,

Any relevant materials for the doubt ?

Hi Karthik,

Right now I can't get the integration scheme but all I can say if you have observed we are coupling transient Dynamic and non linear where large displacements are involved.
