How can i use subroutine to simulate the highly cyclic response of RC beams

[Dennisjin]

Greetings.

I am neu with Abaqus. And i am trying to use abaqus subroutine to simulate the concrete behavior under high Repetition of Forces. That means a RC beam with fatige-Problem. which subroutine can i use for this Simulation? And how can i define the concrete behavior? Did you guys know any mechanical formulae to describe the evolution of plasticity and damage uder fatigue?

Any suggestions about this question, would be really appreciated.
Thank you so much for your reading and your time!

IF you are looking to create a material constitutive model to describe the concrete behavior under high repetition of forces, you'd better go and look UMAT subroutine. Abaqus manual has explanation and examples.
