We address non-contact detection of defects in the railway rails under their dynamic loading and propose to combine digital image correlation (DIC) and finite element modeling (FEM). We show that accurate model of defect-free rail operating at the same loading conditions as the inspected one provides a reliable reference for experimental data. In this study, we tested the rail samples with artificial and fatigue defects under cyclic loading, calculated displacement and stress distributions at different locations of the cracks via DIC and validated the obtained results by FEM. The proposed DIC-FEM approach demonstrates high sensitivity to fatigue cracks and can be effectively used for remote control of rails as well as for non-destructive testing of various other objects operating under dynamic loads.

Manually, pepper peeling uses water flowing in the river for 8-14 days that cause the river to become polluted by pepper peel and cause a bad smell. A pepper peeling machine is a tool to peeling pepper that has a system using two dishes consisting of a fixed top dish and a rotating bottom dish. A shaft is used to rotate the bottom dish with 14.58 rpm rotation, and it requires 1 kW electric motor with 1400 rpm rotation that is transmitted by reducer ratio of 23.3:1 and a bevel gear ratio of 1.6: 1. The shaft must be analyzed to determine its ability where the material is carbon steel material that has yield strength 350 MPa and is supported by two angular contact bearings which function as pin constraints and frictionless constraints. The shaft was analyzed using stress analysis with static analysis method using Autodesk Inventor Version 2019 software. Based on the analysis results, a minimum von mises stress of the shaft is 0.00 MPa and a maximum of 826.57 MPa on the diameter of 25 mm, minimum safety factors of 0.42 on the diameter of 25 mm and a maximum of 15. In Von-Mises stress and safety factor, the diameter of a shaft is not strong enough to withstand the load. To be able to meet the determined yield strength with a minimum safety factor of 1, the minimum diameter needed is 34.05 mm with a safety factor of 1.1. Using this machine, pepper peeling that done in the river can reduce river pollution.
