In this tutorial, the Simulation curved steel–UHPC–steel double skin composite panel under bending load in Abaqus has been investigated. The UHPC panel is modeled as a three-dimensional solid part. The steel skins are modeled as three-dimensional shell parts. You can see a figure of the assembled parts below
Steel–UHPC–steel double skin composite panels are structural elements that comprise two external steel plates infilled with a concrete core. For accurate modelling of behavior of concrete, it is essential to adopt an appropriate material model to define the compressive and tensile behavior of concrete. There are several kinds of concrete model available for simulating the nonlinear behavior of concrete in ABAQUS software. The Concrete Damage Plasticity model is used to define UHPC panel behavior in compression and tension load. The Tensile and compressive damage also used to show the crack propagation. The elastic-plastic model with ductile damage criterion is selected for the steel skins. In this tutorial, the static and dynamic solver are used separately in two simulation. The differences between static solver and explicit is negligible. The surface to surface contact algorithm with contact property is assigned to the contact zone between rigid body and top steel skin. The contact between UHPC and steel skins are considered as surface to surface contact in the static general model and general contact in the explicit model with cohesive behavior. The fixed boundary condition is assigned to the two ends of the panel and displacement as a load to the top rigid body. The mesh should be fine to obtain correct results
After both simulation( static and explicit) all results such as stress, strain, tensile and compressive damage, force-displacement diagram, and … are available. You can see some figures for both simulation below
