FEA analysis of thin steel sheet with different locations of reinforcing ribs created by local laser treatment
Santrauka
The results of FEA simulations of the tensile test established that local laser processing can be used to resist tensile loads thin sheet steel S550MC by up to 38 %, as an alternative to the application of complex geometric shapes or additional strengthening elements. The FEA method can be used for the prediction of the required laser treatment area - geometry and localization of processed area, depth of laser penetration, orientation, and quantity of laser tracks.
