I want to model rc element subjected to cyclic loading, How do I enter hysteresis data in the material model? I want to use Mander's 1988 model to get data for concrete. I dont know how to enter it in abaqus.
Dear Naik
You need to use the UMAT option and link the Fortran code of the hysteretic constitutive model of concrete to ABAQUS.
Mehdi Ebadi-Jamkhaneh sir, can you please share any resource that I can refer?
Hello Akshay Naik,
There are different constitutive material models available in Abaqus to define material property definition, you can use one of them like the concrete damaged plasticity (CDP) model for concrete. The CDP model allows variation of strength of the material in tension and compression with different damage parameters to model the degradation of strength and stiffness. Abaqus requires the yield stress of the material and the values of damage parameters (dt and dc) in the input as a function of inelastic strain and cracking strain under compression and tension, respectively. So, in that, you can use the Mander’s stress-strain model for the compressive behaviour of the concrete material.
