I am working on composite pipe haveing steel wires as reinforcment and rubber.Query1: I want to simulate only plastic deformation .I tried to use voce law but it activates at certain increasd pressure. Not at low pressure where we have less stresses developed .I tried with prestress equal to yield stress so voce law activates but a lot more deformation observed.Suggest  me any material which gives me directly plastic propety of steel.I have uniaxial experimental data of my materials.Query 2:I want to apply working pressure and burst pressure in mechanical apdl ? is it possible to apply in  working pressure and burst pressure because working pressure involves pressure applied for soem minutes and burst pressure includes pressure applied in steps then keep applying each pressure for some time ?
