ABAQUS software has an extensive library of adhesive elements for modeling the behavior of adhesive joints, joint surfaces in composites, and other areas where integrity and strength of bonding are important.
In this package, tips will be given on how to choose the right adhesive element for the problem, how to apply these elements to engineering problems, define the basic geometry of the adhesive elements, and how to define the mechanical behavior of these elements in ABAQUS.
This training package comprehensively examines the cohesive simulation in ABAQUS. The focus of this training package is on modeling by the traction-separation method. Two methods of element-based and surface-based modeling are used to simulate the adhesive, each of which has advantages and disadvantages. The theories used in this package include all adhesive behaviors, including the elastic zone, damage initiation, progressive damage, and element removal. All equations, damage initiation criteria, and adhesive damage progression are also fully described in this package. In this training package, various examples for each of these methods have been used. Also, note that the use of solvent is effective on how to use these two methods. It should be noted that like other issues, if you use an implicit solver, sometimes there is a problem in convergence, and in this package, solutions to the divergence problem are also presented.
Patricia Brown –
I learned everything I needed to know about cohesive modeling. English with a native accent, subtitles, and files helped me a lot. thank you
