SORPAS 2D v15.0
Release date – July 2023
SORPAS 2D.welding and 2D.joining v15.0 is available. This new version upgrade includes enhanced current setting for Excel batch planning, new LME crack risk prediction, improved fracture and friction models in joining, and improvements in splash prediction.
Advanced current setting
With new simulation mode option and weld program database, you can easily customize set of simulations in the Excel batch planning.
LME crack risk prediction
New function for modeling and prediction of LME crack risk is developed.
Higher strength materials with more brittle fracture behaviors can be simulated with improved fracture models as well as friction models.
- Splash (expulsion) prediction model improved – It is especially improved for three sheet combinations. This also improves the function of Weld Planning for prediction of optimal welding parameters.
- Simulation of force increase due to thermal expansions – Thermal expansions will result in force increase due to elastic reaction of the welding machine frame.
- Distortion around the weld nugget in Excel batch – New output for the final strain in each sheet will be output to Excel sheet.
- Hardness curve – New function developed for plotting the hardness traverse curve on an oblique line defined with 4 points referring to ISO 14271:2017.
- Import weld program into database by Excel datasheet.
SORPAS 3D v7.0
Release date – July 2023
SORPAS® 3D.welding and 3D.testing v7.0 is available now. This new upgrade includes the improved Sparse solver, and improvements for more complex resistance welding processes such as seam welding, fusing, and battery welding.
The faster new sparse solver
With further improvement in stability and consistency, the new sparse solver can substantially reduce computation time for larger models.
Seam welding simulation
Special improvements in electrode gap closing make a more realistic simulation of seam welding.
Auto cooling to 50°C
With this function, the welding and post-weld cooling can be completed automatically to obtain the final material properties before weld strength testing.
- The new function for automatic soft touching at the start of welding can get more realistic contact of electrodes, especially in the case of some electrical applications such as fusing (hot staking).
- The results of stress and strain at the end of welding based on different options of models (thermal stresses and unloading/residuals) are automatically included in the subsequent weld strength testing simulation.
- New fracture models enable brittle fracture of AHSS.
- New models for solid-state bonding are implemented to make it possible for strength testing of adhesive bonding and weld bonding.
- New models for hat profile beams are implemented in addition to the templates of all standard test coupons.
- Weld nugget and all material properties after welding are transferred from SORPAS 2D® to SORPAS® 3D.testing
- The 3D model for KSII testing can be set with rotation in order to set testing direction with different angles.
- New functions added to build objects in the library: add blocks using parameters, load another object into the object, and mirror an object in the library.
