The team of ar engineers GmbH has released the official version of their online calculation platform for bonded joints – calcbond.

What is the mission of calcbond?
The mission of calcbond is to simplify the use of adhesives and to provide a reliable solution for adhesive bonded joints calculations.

What makes calcbond unique?
The calcbond ecosystem consists of a comprehensive material data base and automated use cases with state-of-the-art methods in analytical and numerical calculation. Moreover, the calcbond platform supports on-demand project handling with zero waste time.

For which users is calcbond intended?
calcbond was developed for all users who want to calculate adhesive bonds quickly and straightforward. No in-depth knowledge of bonded joints is required.

What functions offers calcbond?

1. Material cards
Choose from a comprehensive database of different adhesives and find the right adhesive for your application. Find out about the areas of application, processing and curing mechanism. In addition, the material cards contain detailed data on the mechanical properties of the adhesive, even at different temperatures, in the form of tables and diagrams. A particular advantage is the comparability of the adhesives and the subsequent transfer of the data into the calculation with just one click.



2. Analytical calculation
The team of ar engineers GmbH succeeded in bringing the complexity of adhesive calculations to a user-friendly interface where you get a reliable and fast solution. Analytical calculation models have a particular advantage, as the calculation is carried out within a very short time and therefore a quick assessment of the adhesive layer stresses (shear and peel stresses) can be made.




To represent a wide range of practice-relevant joints and thus provide the appropriate configuration for each user, simple overlapped structural bonds, double L-holders or a general-purpose sandwich model can be used.

Equivalent stresses are also calculated for a quick assessment of the adhesive stress, which can be directly compared with the adhesive tensile strength.


3. Auto FEA

This module enables the user to evaluate 3D adhesive joints using finite element analysis (FEA) for standard use cases. After defining all the necessary data, the user submits the simulation request, which is promptly processed by ar engineers. The user will be able to evaluate the joint deformation as well as adherend and adhesive stresses:



In this way, users can go from defining the problem to evaluating the results of their adhesive joint with minimal effort – and all within a few minutes! The automatically generated analysis report helps customers to standardize their internal communications and facilitate the product certification process.


If you are interested, you can try out the functions of the platform. The trial period will be until the July 14th:
