Study on vibration of the saw cylinder and its critical speed [PDF]
E3S Web of Conferences, 2023 The force impact of the 130 saw cylinder of gins 4DP-130 and 5DP-130 was studied. It was determined that due to the significant weight of the saw cylinder, when it is rotated at 730 rpm, its radial runout increases, leading to shaft deflection and wear ...

An Anisotropic Damage Model for Prediction of Ductile Fracture during Cold-Forging
Metals, 2022 Researchers have formulated equations of ductile fracture to simulate and predict defects in cold-forged parts, e.g., the Cockcroft–Latham criterion. However, these equations are not applicable to certain cases of fracture in forged products.
