En Our skills in numerical simulations
The welded assembly model
The welded seams behavior is particularly complicated to estimate with a numerical simulation.
Homogeneous modeling too simplistic
The metallurgical state changes due to the welding process make any homogeneous modeling too simplistic to be representative of reality.
In depth and costly solid geometric model
Local stress concentrations require an in depth and costly solid geometric model, which can be disadvantageous, especially if the welded assembly has a significant number of welded seams.
A specific methodology
The engineers of AROBAS Technologies implement a model and calculation methodology for welded seams (sheet or streamlined steel)
A realistic representation
To represent in a realistic manner the welded connection stiffness (using a shell element model)
To calculate the static or fatigue behavior
Based on analytical stress calculations, considering the nodal efforts passing through the finite element model, keeping in mind the EUROCODE 3 standards
To reduce the model
By avoiding an unnecessary detailed solid representation of the welds
A proven method
Compared to other existing similar methods, the one we use has proven to be the best time / results compromise.
