Webtraining – Modeling adhesives with Abaqus

10 Nov, 2022 @ 10:00 am - 11:00 am

During this webtraining 4RealSim will introduce cohesive modeling, the different methods and how it is integrated in Abaqus. Furthermore an introduction will be made to VCCT. This webtraining is part of a series of fracture mechanics sessions (Modeling Material Failure with AbaqusModeling adhesives with Abaqus & Mesh-independent fracture modeling XFEM).
4RealSim believes in continuous Abaqus learning and regularly organizes webtrainings for our customers. Join our webinar and learn more about Abaqus, get more confident in the usage and become more efficient!

Cohesive modeling strategies

Abaqus has two ways to model adhesive behavior: cohesive elements and contact cohesive behavior.

Cohesive elements

Cohesive elements are useful in modeling adhesives, bonded interfaces, gaskets, and rock fracture. The constitutive response of these elements depends on the specific application and is based on certain assumptions about the deformation and stress states that are appropriate for each application area. The nature of the mechanical constitutive response may broadly be classified to be based on the continuum description of the material, the traction-separation description of the interface and the uniaxial stress state appropriate for modeling gaskets and/or laterally unconstrained adhesive patches.

Contact cohesive behavior

Contact cohesive behavior can be used to model a bonded interface, with or without the possibility of damage and failure of the bond, and to model regular contact behavior where the interface is not bonded. Cohesive contact behavior is typically easier to define than modeling the interface using cohesive elements and allows simulation of a wider range of cohesive interactions, such as two sticky surfaces coming into contact during an analysis.


The virtual crack closure technique (VCCT) investigates the onset and propagation of cracking in quasi-static problems. VCCT uses the principles of linear elastic fracture mechanics (LEFM) , so it is appropriate for problems in which brittle crack propagation occurs along predefined surfaces. VCCT is based on the assumption that the strain energy released when a crack is extended by a certain amount is the same as the energy required to close the crack by the same amount.
