      Dear colleague

      In the material properties window as shown here, two meanings of Yield stress and strength is it make different sense or same meaning here?

      Yield strength in the BIH is Ultimate strength and bottom one is yield stress of material is it right or is there any other meaning with it?

      Could you please explain with it.

      Thank you so much

      Hello,nThank you for your question and your patience. The Yield Strength in the Bilinear Isotropic Hardening is the yield point as I have circled here. It is not the ultimate strength.nnFor the Chaboche material model, the yield stress is the initial yield stress. nIf you combine the two material models you can simulate cyclic hardening.nPlease let us know if this answers your question. Thank you.nnRegards,nSea
