hi mohammed,

it is 100 percent necessary to provide the validation for FEM results. it should be experimental or analytical results to validate the FEM.

you can compare your FEM work with experimental or analytical works that has been published already.

best regards,

Yes, it has to be validated.

Whether experimental validation is necessary for such problems solved in Abaqus depends on the specific problem and the journal's requirements. In general, experimental validation is always desirable, but it may not always be feasible or necessary.

For example, if you are simulating a well-known phenomenon with well-defined material properties, then experimental validation may not be necessary. However, if you are simulating a new or complex phenomenon, or if you are using material properties that are not well-characterized, then experimental validation is more important.

The journal's requirements will also play a role in determining whether experimental validation is necessary. Some journals require experimental validation for all numerical simulations, while others may only require it for certain types of simulations.

Ultimately, the decision of whether or not to perform experimental validation is up to the researcher. However, it is important to weigh the pros and cons carefully before making a decision.

Here are some of the pros and cons of experimental validation:

Pros:

• Experimental validation can help to ensure the accuracy of the numerical simulation.
• Experimental validation can help to identify any limitations of the numerical simulation.
• Experimental validation can provide additional insights into the physical phenomenon being simulated.

Cons:

• Experimental validation can be expensive and time-consuming.
• Experimental validation may not always be possible, especially for new or complex phenomena.
• Experimental validation may not always be conclusive, as there may be other factors that affect the results.

In short, YES!!

Experimental validation is often considered an important aspect of scientific publications involving problems solved using Abaqus or any other simulation software. While simulations can provide valuable insights and predictions, experimental validation helps confirm the accuracy and reliability of the simulation results. Including experimental data and validation in your publication can enhance the credibility and impact of your research. However, the extent of validation required may vary based on the nature of the problem and the specific research goals, as pointed out by Yousef Bahrambeigi
