You can take a look at following softwares

Elmer : https://www.csc.fi/web/elmer

Calculix : http://www.calculix.de/

Nivedan Mahato

you can try COMSOL which have good material library also can use ANSYS both software can download from getintopc

Neeraj Suthar

Dear Sir,

You can try ABAQUS, ANSYS, COMSOL Multiphysics, OpenFOAM , Autodesk.

ABAQUS is generally used for academic purposes where ANSYS is used for industrial purpose.

Esra Yuksel

Dear Hulas,

You can try DEFORM software for machining operations. Mesh regeneration will be important for you, and DEFORM will enable this requirement .However, it is not a open source software, though you can create your own material library via Fortran etc. and implement it to DEFORM.

Andrew Smyrek

Hulas, you should have a look at FreeCAD it is open source and as the name implies free. Joko engineering has run a direct comparison of FreeCAD against Solidworks for FEA and was impressed by the results himself. Which is most likely why he published the video on Youtube. Everyone should try it for the CAD modelling alone!

Bogdan Alexandru Chirita

I think some of the answers are not right. As someone already said, ABAQUS, ANSYS and others are not open source.

However Abaqus is offering free student licenses with limited capability.

K V Arun

As bogdan alexandru mentioned Abaqus is available. Where you can solve any static, dynamic, nonlinear priblems. Also you can cide your own element... Wgich is most essential in fracture mechanics and crack growth analysis

Stefan B Lindström

FEniCS is nice. There is no GUI. You formulate the weak form directly using Python. Plot the results using Paraview.

Maurizio Sciancalepore

You're definitely not allowed to use the student versions of ANSYS and ABAQUS for conducting researches and obviously also for commercial purposes. These versions are solely intended for students or (I'd guess) FEM amateurs with a lot of spare time. Please let us not confuse the ability to download a fully or partially working piece of software with the right to use it and publish results obtained from it. It's highly misleading.
