Скачать или смотреть ANSYS Workbench: Bond-Slip Behavior Between Rebar and Concrete (SOLID65)-Including Concrete Cracking

The SOLID65 element in ANSYS Workbench is designed to model concrete behavior, particularly to simulate cracking due to tensile stresses. The process involves defining material properties for both the concrete and the embedded rebar, establishing the appropriate contact and interaction between them. To capture the bond-slip behavior between the rebar and concrete, COMBINE39 elements are used, representing the non-linear spring behavior that simulates how the bond strength evolves and slip occurs as the load increases.
