How can I define the failure of the beam connector as a discrete fastener?

07 June 2024 0 9K Report

I am using the discrete fastener method for an LSF frame, and I want to consider the shear failure of rivets in my simulation. However, when I define lower and upper bounds for shear force, Abaqus releases the elements from the first increments.
