Quick Summary

A constant load-rate test machine is a type of mechanical testing equipment used to determine a material's properties under stress. In this machine, loads are applied at a consistent rate, typically using a hydraulic ram that pumps oil at a steady pace. This controlled application of force allows for precise measurement of how a material deforms or elongates under tension, or how it responds to crushing forces in compression tests.1

These tests are crucial for designers to understand a material's breaking point and its behavior under expected stresses, helping to prevent failure in structures and machines. The data gathered from these tests, such as strain (change in length per unit length), is vital for selecting appropriate materials for various applications.21

Static tension and compression tests
Constant load-rate test machines employ separate load and measurement units; loads are generally applied by means of a hydraulic ram into which oil is pumped at a constant rate. Constant displacement-rate testing machines are generally driven by gear-screws.
