In this tutorial, Numerical simulation of three-point bending of the composite panel(ceramic-Steel-Aluminum) in Abaqus has been investigated. The ceramic and steel plates are modeled as a three-dimensional solid part. The aluminum core with honeycomb shape is modeled as a three-dimensional shell part. Three rigid bodies are used to define hydraulic jack and boundary zone. Composite sandwich structures have been applied in many engineering applications due to their lightweight, high stiffness, good damage tolerance, and energy-absorbing capacity. You can see a figure of the assembled parts below
To model steel behavior, elastic and Johnson-Cook plasticity is used. The Johnson-Cook plasticity model is suitable for high-strain-rate deformation of many materials, including most metals and it is a particular type of Mises plasticity model with analytical forms of the hardening law and rate dependence. To model, the ceramic material Johnson-Holmquist model is implied. This model assumes that the damage variable increases progressively with plastic deformation. The aluminum core material is model as a elastic-plastic material. The dynamic explicit step is appropriate for this type of analysis. The ideal cor perfect contact is considered among the deformable part and general contact with friction as a contact property. The surface to surface contacts is used to define contacts among the rigid bodies with ceramic and steel plates. The fixed boundary is assigned to the two bottom rigid bodies and displacement to the top rigid body. The mesh should be fine to achieve good results
After the simulation, all results such as failure and damage of the ceramic plate, aluminum core crushing, stress, strain, force-displacement diagram, and …are obtainable. You can see some figures for the results below
