In this tutorial, the Simulation of cyclic loading of a steel beam reinforced with epoxy and CFRP in Abaqus has been done. The steel beam is modeled as a three-dimensional shell part. The epoxy and CFRP are modeled as three-dimensional solid parts. You can see a figure of the assembled parts below
For the most part, plastic analysis and design have in the past been directed toward the study of proportional, Monotonically increasing loading to failure. This type of loading is not entirely realistic for many applications, However. The concepts of a shakedown analysis. while enlarging the scope of plastic analysis, results in a structure that ultimately responds elastically, after a few cycles of inelastic action. Severe earthquakes, on the other hand, may induce considerable repeated inelastic action in a structure, especially at the joints. This has motivated the study of steel members and connections subjected to repeated and reversed loading
To model steel hardening behavior under cyclic loading, Abaqus recommends some models like kinematic or combine hardening to consider the effect of each cycle in the stress-strain curve. Epoxy is modeled as elastic with damage behavior as traction-separation law. The CFRP is modeled as an elastic model.
The general static step with some changes in convergence is considered. The proper interaction between the contact surfaces and constraints is assigned to all parts. The mesh should be fine to obtain the correct results
After the simulation, all results such as stress, strain, damage, hysteresis diagram, and others are available. You can see some figures for the results below
