Stress Relief Heat Treatment: Finite Element Simulation
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Stress relieving reduces residual stresses in the assembly after welding.The Stress Relief Heat Treatment performed including definition of time-temperature curves for heating, holding and cooling phases with individual convective heat transfer to environment definition. FEA Stress relief is modeled taking into account two mechanisms: Stress relaxation due to decreased yield stress of material during heating - Time-dependent creep properties of the material
Enteknograte engineers simulate the Welding with innovative CAE and virtual prototyping available in the non-linear structural codes LS-DYNA, Ansys, Comsol, Simufact Welding and ABAQUS. We are experienced with FEA Welding simulation.
Enteknograte Engineers can simulate any type of welding such as Arc Welding, laser Beam Welding, RSW, FSW and transfer the results of welding simulation for next simulation like NVH, Crash test, Tension, Compression, shear test and fatigue simulation.
Why we use Simufact as default for welding simulation
Simufact Welding predicts distortions and residual stresses by virtually try-outs and helps the user to determine appropriate strategies to minimize them. It is the only simulation software which automatically considers the complex contact situation between the components, which in turn allows conclusions about the properties of the weld seam, in particular its strength, to be drawn. Simufact Welding achieves this by calculating the microstructural properties within the heat-affected zone, which also gives the user a valuable insight into identifying welding defects, such as hot cracks in the simulation, and how to avoid them in practice.
Enteknograte Engineers simulate any type of welding with any level of complexity:
• Arc Welding
• Electron Beam Welding
• Laser Beam Welding
• RSW (Resistance Spot Welding)
• FSW (Friction Stir Welding)
• Pressure Welding
• Stress Relief Heat Treatment
• Fatigue Life of Welded Structures
• NVH, Crash test, Tension, Compression and shear test behavior of Welded Structures
