Topic: Modelling four point bending test problem in recording interface stres
I'm simulating a four point bending situation on a reinforced concrete slab using symmetry. I've applied an overlay of high strength concrete over the existing RC slab and have to study the interface between these layers. I'm selecting a monitoring point at the interface at a certain integration point to document the interface stress at that point. While running the analysis ATENA gives me an unexpected error without any specific error message. But if I try to document any other stress value like shear stress then it works. I still need the interface stress values for my analysis. Can anyone help me in this regard?
