    Hello @HK2204 ,

    this is the main goal of FE analysis,especially mechanical analysis, to evalate how changes of meterial, part design, … will affect results such as displacements, stress

    Hope that help,

    Stress will change if the material is different but the model's configuration remains the same (such as the connection and boundary condition).

    But according to Formula of Stress:-

    Stress does not depended on material. Please respond valuable feedback.

    Hello again,

    if you look at the formula, you can go further and look at M formula, then you will see that it is material dependant

    Hello sir,

    But bending moment dose not depend on material property,

    Hello again,

    sure, bending moment is material independant.

    Nevertheless at post-processing, you are generally not post-processing stress coming from bending moment, but stress over the element, which eventually will be dependant of material data

    Best Regards,

    Michael
