The behavior of an asymmetric bladed rotor was investigated in this study. which performs solid-solid, liquid-liquid, liquid-solid separation processes is part the decanter machine and named as screw conveyor. purpose study to determine dynamics on free conditions for future development blade assembled rotors. It important designer natural frequencies so that some precautions can be taken durin...

This work examines the crack initiation and propagation in Prestressed Concrete (PC) beams by a combined experimental numerical approach. Four-point bending tests performed on PC sleepers lead to formation of multiple cracks, number that depends specimen. The location each fracture its growth with time is monitored Digital Image Correlation (DIC). experiments are simulated finite element approa...
