Hi @Vaibhav25

Please see this plot with Yield-plastic

Hi Prakash thanks for the reply.

In this graph the force values that is the interface/contact force is coming close to my experimental values. But again if you see the deformation in the structure the elements at the top are getting distorted. why is that. What was the run time you gave? and you used imposed displacement only?

And one thing this time the elements are not folding inside like the previous one which is good.

And how were you able to get this graph.

 

Thanks again.

I will share the modified model with you. 

 I had to stop the run in between as it is taking time and resource of my machine. 

 

I did use the model shared by you as it is except changes are done in the curve. 

 

Please correlate the model dimensions and deformation pattern and compare at the end of the analysis.

hi.

Iam trying to do the analysis with a rigid wall this time. 

But the problem is no deformation is taking place how much ever time i give and velocity. Mass i gave same as anvil.

Hi Vaibhav,

 

How do you come up with the velocity?

 

Can you increase the velocity and check if that helps?

Hi. 

I tried by giving a velocity of 100mm/sec. Very negligible deformation is happening and it looks like the rigid wall is moving to and fro as in the h3D file the deformation contour is coming and going. 

I am attaching the h3D file. The analysis not complete but still attaching.
