Hi,

 

i am doing rivet joint analysis in radioss and here both sheet metals are steel only. but in result plate is simulating in wave form as shown in below picture.

 

How can i avoid this kind of simulation?

 

 

Thanks and Regards

    Hi,

    What is the loading and boundary condition used?

    Thickness of plates?

    Hi Narasimhamurthy,

    Please elaborate more on the objective of the simulation and also the modelling parameters.

    each sheet metal thickness is 0.28 mm

     

    100N tensile load  applied at one end and other end is fixed.

    Hi Narasimhamurthy,

    Is there any pretension applied in the bolt?.

    Can you share the model files (_0000.rad and _0001.rad) through the secure file transfer link in the signature so that we will have a review and workaround on your model.

    Here no retention load. only tensile load. 

     

    please find attached model files.

    Hi Narasimhamurthy,

    Can you rerun the analysis with the attached file and update.

    The penetrations in the model were cleared. The model has a very low time step and so a time step is imposed in the engine file. All other modeling parameters remains the same.
