Hi all, I am trying to perform a dynamic analysis in ANSYS by simulating the offshore pile structure driven by a hydraulic hammer and need to determine the maximum acceleration expected on the pile due to the hammering action. Does ANSYS have the capability to perform an implicit dynamic analysis when i have the Hammer capacity and blow counts and other pile, soil stiffnesses as my input? Which ANSYS module fits this to find the maximum accelerations expected due to hammering?

Hello Madhan,

Yes, you can use "Transient Structural" analysis system. It is an implicit dynamics analysis system and you can define equivalent soil stiffness for your pile.

Hi Rezamousavi, thanks for your prompt reply. How this 'implicit' dyanmics differs with 'Explicit' analysis as i noticed on the product brouchure it most referring to drop and impact testing which i can use for my hammer impact analyis. Bit of insight of their difference will guide me through on their selection and accuracy of the accelerations which we are estimated to have around +/-6g.

Thanks in advance.
