Modeling of softening effects

New function for modeling and prediction of softening effects in hardness distribution around the HAZ after spot welding of high strength steels.

SORPAS 2D input wizard for joining

New Input wizard for joining

Input wizard makes it easy to build simulation model for Joining (SPR and clinching) by selecting rivet, die and other objects from database.

  • Excel batch planning – Improvements with new options and more detailed output results in Excel batch planning.
  • Calculations of solidification factors – New functions on calculations of solidification factors “R” and “G” with all related results saved in the new result file: “filename_RG.csv”. New material data “dT.RG” is implemented in the Material Database, which is used only to off-set the Solidus and Liquidus exclusively for calculations of solidification factors “R” and “G”. Read more related research using this new features.
  • Improved calculation for process range – Systematic improvements on Weld planning and Optimizations for predicting better process range with optimal welding process parameters.
  • Improvement on residual calculation – Systematic improvements on calculations of residual stresses and residual strains with considerations of phase transformations and dynamic coupling of thermal effects during heating and cooling processes.
  • Special improvements for simulation in Hybrid mode – It is possible to simulate welding and joining in the same process at the same time.

SORPAS 3D v6.0

Release date – September 2021

SORPAS 3D.welding and 3D.testing v14.0 is available now. This new version upgrade includes new equation solver, improvement in calculations of residuals during cooling time and fracture calculations during strength testing, and new user-friendly functions for preparing 3D models and analyzing the results.

new solver option in SORPAS 3D

New equation solver available

New ‘Sparse’ solver reduces the calculation time up to 75% for big size model and projection welding based on in-house test. The number can vary depending on the simulation condition.
