Simulation air blast explosion over a timber wood beam reinforced with CFRP in Abaqus

In this tutorial, the Simulation air blast explosion over a timber wood beam reinforced with CFRP in Abaqus has been investigated. The two wood beam layers are modeled as three-dimensional solid parts. The CFRP sheet is modeled as a three dimensional shell part. You can see a figure of the assembled parts below

Damage initiation refers to the onset of degradation at a material point. In Abaqus the damage initiation criteria for fiber-reinforced composites are based on Hashin’s theory.These criteria consider four different damage initiation mechanisms: fiber tension, fiber compression, matrix tension, and matrix compression. To model CFRP material, the elastic model with fail stress option and Hashin’s damage criterion are used. To model wood behavior, the engineering elasticity with plastic model is selected

The dynamic explicit step is appropriate for this type of analysis. The cohesive interaction between the wood layers and CFRP with wood is selected, To define cohesive surface interaction, the stiffness and the damage model are considered. The CONWEP air blast load is used in this tutorial to consider the blast load on the timber wood. The fixed boundary condition is assigned to the two ends of the beam. The mesh should be fine to obtain the correct results

After the simulation, all results such as stress, strain, damage, failure, diagram are available. You can see some figure from the results below
