This study investigates the effect of pulsating cyclic fatigue loading on the internal stress of silicon steel material. A comparative analysis is conducted between the loaded material and the original material before treatment. The findings indicate that pulsating cyclic fatigue loading leads to a decrease in the residual stress of the material and an increase in its elongation. albe... https://parisnaturalfoodes.shop/product-category/vit-d3-2500iu/
