This chapter discusses features related to contact and interaction modeling. It provides an overview of the following enhancements:

• “Beam-to-surface and beam-to-beam contact,” Section 10.1

• “Enhanced convergence behavior for Abaqus/Standard contact analyses,” Section 10.2

• “Contact pressure–dependent constraint enforcement in perturbation steps,” Section 10.3

• “Contact thickness enhancements,” Section 10.4

• “Temperature and field-variable dependence of the friction coefficient,” Section 10.5

• “User-defined tracking thickness for user subroutine VUINTER,” Section 10.6
