First principal strain in a representative element within the internal os for increasing IUP while parameterizing the fetal membrane modulus from 0.1 to 100 MPa. With increasing membrane stiffness, strain levels in the cervix decrease. Literature values for membrane stiffness vary between 1 and 40 MPa.
