We used a finite element modeling platform i.e. Abaqus 6.11 to simulate the indentation test of a cartilage specimen introduced as a poroelastic material. We developed an Abaqus user subroutine to identify the contact between the cartilage and the indenter. In this method, when contact stress on the cartilage's surface is greater than a threshold value, fluid flow is forced to stop. The developed user subroutine processed the information received from the solver in each iteration and created a common b
