Hi Pratik,

This seems to be a quasistatic analysis and being solved in radioss. As George said, try with imposed displacement as boundary condition.

Use curve with foll. values in first trial run:

Time  Displacment (mm)

0.0          0.0

 

0.1          100

 

Hi @George P Johnson @gopal_rathore

How to decide that imposed displacement(0-100 mm) to be applied with in 0.1 sec ?

Hi Karthic,

This value of 100ms was provided as an example. Based on user requirements we ramp the load in a short time or ramp it in more time.

You can go through https://altairuniversity.com/learning-library/7-guidelines-to-apply-quasi-static-load-in-explicit-simulation/ which provides basic guidelines on quasi static loading in explicit analysis.
