In this tutorial, the Simulation air blast explosion over a Wood-Concrete slab reinforced with BFRP lamina in Abaqus has been investigated. The wood-concrete part is modeled as a three-dimensional solid part. The Basalt Fiber Reinforced Plastic( BFRP) is model as a shell part with eight layers. The steel reinforcement which is embedded inside the concrete is modeled as a three-dimensional wire part. You can see a figure of the assembled parts below
Energy and environmental issues are major concerns in the global perspective of sustainable development. 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.
The Concrete Damage Plasticity Model (CPDM) available in the Abaqus code is adapted and used to model the mechanical behavior of the wood-cement composite. 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 tensile and compressive stress-strain and damage are used in this analysis. The steel reinforcement is modeled as an elastic and plastic material. The BFRP lamina is modeled as an elastic material lamina type and also the Hashin’s damage criterion to consider damage in the fiber is selected. The dynamic explicit step is appropriate for this type of analysis. The steel reinforcements are embedded inside the concrete host and also the perfect contact is assumed between the BFRP and wood-concrete part. The fixed boundary is assigned to two sides of the slab. The mesh should be fine to obtain correct results
After the simulation, all results such as stress, strain, tensile and compressive damage, the BFRP damage, reaction force diagram, and… are available. You can see some figures for the results below
