Literature Review on Designs and Methods of Fatigue Testing

Abstract

The fatigue testing machine is special equipment specially used for testing the fatigue strength of various materials and components. These machines apply cyclic loads to materials, simulating the conditions under which materials can fail due to repeated stress. These testing machines are commonly used industries in such as aerospace, automotive, civil engineering, and materials science. The primary purpose of the fatigue testing machine is to determine how many cycles a material or component can withstand before failing. The data obtained from these tests is used to assess the design, performance and durability of the product, identify potential weaknesses and make necessary improvements to the design or production process. Fatigue testing machines come in many forms, from simple bench top machines to large hydraulic systems capable of producing millions of pounds of force. These machines are often equipped with advanced sensors and software systems that collect and analyse data and display the results in real time. In general, fatigue testing machines play a key role in ensuring the quality, reliability and safety of materials and products used in various industries. It is therefore an essential tool for researchers, engineers and manufacturers involved in the development and testing of new products. In this article, fatigue testing machines are first classified according to certain characteristics, including purpose, type of load, and type of load application, transmission, and control system. Because load systems play a key role in defining the design characteristics, range, and limitations of a tester, these systems are described in detail here. Typical examples of test rigs built for uniaxial and multiracial loading are presented.
