To be accurate, Material's Young modulus is different according to pressing and pulling.

Can I set the two value for 1 material?

    Hi VAL1

     

    It is possible if you use an orthotropic material card.

    According to online help MAT 3 has the capability to apply youngs modulus in different directions.

    Have a check at the different card capabilities from the online help

    Thank you!

    I can use Mat3 for orthotropic material.

    But I mean the attached file. in case of Al, If it is stretched 73GPa, pressing 71GPa.

    what card should I use in this situation?

    Hello VAL1,

    If you performing simple tension & compression individually, you can create two material with different E value. Make two prop & two loadstep.
