Simulation four-point bending of a composite beam(Wood-Cement) in Abaqus

In this tutorial, the Simulation four-point bending of a composite beam(Wood-Cement) in Abaqus has been studied. The wood-cement beam is modeled as a three-dimensional solid part. The four rigid bodies are modeled as three-dimension rigid shell parts. You can see a figure of the assembled part below

Energy and environmental issues are major concerns in the global perspective of sustainable  development. The housing sector is particularly energy-intensive. It is a major greenhouse gas  emitter and consumer of natural resources. This context has led the scientific community to  reassess the performance of building materials on the basis of embodied energy and  environmental impact. Bio-sourced materials combined with a cementitious matrix offer an interesting alternative  to traditional construction materials. They constitute an interesting economic and ecological  solution. Biomaterials such as wood fibers can be sourced from recycled timber or from  sustainably managed forests. They are inexpensive to produce, and environmentally friendly.  They can sequester carbon in the construction. They are generally highly porous with a low  apparent density and a complex architecture marked by a multi-scale porosity. These  geometrical characteristics result in a high capacity to absorb sounds and have hygro-thermal  transfer ability. Based on the above observation, it can be seen that the behavior is typical of a concrete  material. As such, it can be easily modelled using the Concrete Damage Plasticity Model (CDPM) available in Abaqus. The CDPM has the potential to represent the complete  inelastic behavior of the wood-concrete material in both tension and compression, including  damage effects. The general static step with some changes in the convergence model is selected. The surface to surface interaction with contact property is assigned to the contact zones between beam and rigid bodies. The fixed boundary condition is assigned to the to bottom rigid bodies. The displacement as a load is applied to the two top rigid bodies. The mesh should be fine to obtain good crack pattern and growth

After the simulation, all results such as stress, strain, tensile and compressive damage, force-displacement diagram, and … are available. You can see some figures for the results below
