SORPAS® 3D.testing

SORPAS® 3D.testing is a tool for weld strength testing. The key applications of SORPAS® 3D.testing are the following:

  • To evaluate the weld and joint strengths based on simulations with actual welding and joining conditions.
  • To provide the weld and joint strengths dependent on actual materials and welding conditions to the subsequent structural and crash simulations.

You can import simulations from SORPAS® 2D.welding, 2D.joining, and 3D.welding if you also buy the SORPAS® 2D3D.link. Read more about that here.

A common method to evaluate the weld joint quality is by destructive testing to obtain the maximum breaking force in various loading modes and to obtain the failure modes (plug or interfacial failure).

SORPAS® 3D.testing can combine simulation of resistance welding process  and mechanical joining with weld strength tests:

  • Tensile shear test
  • Cross tension test
  • Axial tensile test
  • Peel (or bending) test
  • Torsion test

CAE/CAD engineers doing crash simulations need to implement weld joints with realistic weld strengths depending on actual materials and welding production processes. SORPAS® 3D.testing can output weld strength results to crash simulation models such as Abaqus and others.

Templates for testing

The software provides templates for creating standard testing workpieces by defining the geometric parameters. By entering a few parameters, users can easily create a workpiece for Cross tension test, Shear test, KSII test, and Peel test.

Below you find some examples of weld strength testing by SORPAS® 3D.testing. The simulation results of the weld strength testing with failure modes as well as the load-displacement curve with maximum braking force.
