Simulation bending test of a composite beam(wood-UHPC-Steel) in Abaqus

In this tutorial, the Simulation bending test of a composite beam(wood-UHPC-Steel) in Abaqus has been done. The wood is modeled as a three-dimensional solid part with two layers, the top layer is in compression, and the bottom is in tension. The Ultra-High-Performance-Concrete is modeled as a three-dimensional solid part. The steel cover is modeled as a shell part. You can see a figure of the assembled parts below

To model the UHPC material, the Concrete Damaged Plasticity is selected. The model is a continuum, plasticity-based, damage model for concrete. It assumes that the main two failure mechanisms are tensile cracking and compressive crushing of the concrete material

The elastic-plastic behavior with Hill’s function coefficients is considered to model wood behavior under tension and compression. To model steel material, the elastic-plastic data with ductile damage criterion is selected

The dynamic explicit step with a general contact capability is used. The contact among the internal surfaces is assumed as the perfect contact. The surface to surface contact with friction as contact property is used to define the contact between the rigid body and steel cover. The proper boundary conditions and mesh are assigned to all parts. To consider the full failure of the concrete, in second model, the strain failure model is considered to observe the full failure of the concrete

After the simulation, stress, strain, tension, and compression damage, force-displacement diagram, wood bending, plastic strain, and other results are available. You can see some figures for the results below
