Using Pretension manager

hiranwale_bharat

Hello Everyone

 

I have been trying to use pretension manager in which I gave the value of pretension on the contact surface as 20 (just for trial)

I am using MPA system for units. This was followed by a static subcase.

 

During results I found that deflection due to preload is much higher( of the order of 10e5). I reduced the load value to 2 still the deflection was of the order 10e3.

 

 I have checked my model and everything is fine (load,constraints etc).

 

Can anyone tell me what is the solution for this problem?

 

Regards,

Bharat

Hi Bharat,

 

Can you share the ,out file?

Hello Prakash,

 

I am sorry to say that I can not share the out file with you.

 

But I will define the problem briefly. For trying to use the pretension manager I have taken a simple rectangular block of arbitrary dimensions. Defined a contact surface on the faces of the elements which are below the top surface of the block. In pretension manager I have defined forces and all other things. For the value of 50N in pretension manager i got displacement of around 10e7, and for force of 10e-10, I received a disp. of e-3.

 

Hope you understand the problem.

 

Thanks and Regards,

Bharat
