Product Overview:

In this tutorial, we investigate the dynamic pullout of a steel plate from a reinforced concrete (RC) beam using Abaqus. Both the steel plate and concrete beam are modeled as three-dimensional solid parts, while the reinforcing bars and strips are represented as three-dimensional wire components.

For the steel plate, bars, and strips, an elastic-plastic model with ductile damage behavior is utilized. To accurately capture concrete behavior under dynamic loading, various material models available in Abaqus are employed. Some of these models may require an input file or subroutine code for customization. In this simulation, the concrete exhibits brittle failure and fracture characteristics.

The analysis is conducted using a dynamic explicit step, incorporating a mass scaling technique to enhance stability during the simulation. Two contact definitions are available for the interface between the steel plate and the concrete beam: ideal contact (perfect contact) and surface-to-surface contact with specified contact properties. The reinforcing bars and strips are embedded within the concrete matrix. For boundary conditions, a fixed condition is applied to the sides of the beam, while displacement with an amplitude function is imposed on the steel plate. It’s essential to use a fine mesh, particularly in the contact zone, to ensure accurate results.

Upon completion of the simulation, a variety of results including failure and damage patterns, stress distribution, strain metrics, and force diagrams are generated.
