Upper Crosshead and Lower Crosshead. The upper crosshead is used to clamp one end of the test specimen. The lower crosshead in the load frame is the movable crosshead whose screws can be loosened for height adjustment and tightened. Both the crossheads have a tapered slot at the center.

In the present work was study the analysis of composite crosshead behavior or load modules of universal testing machine, the main objective is to achieve a model that comply the standards to perform destructive tests on samples of metals and non-metals.
Components of Universal Testing Machine. Two primary components make up a universal testing machine as follow: Loading Unit. Control Unit. Loading Unit. The loading unit controls how the test specimen is set up and how much force is applied. The table and crosshead on the left unit make up the loading unit.
Cross head - A movable cross head (crosshead) is controlled to move up or down. Usually this is at a constant speed: sometimes called a constant rate of extension (CRE) machine.
A tensile tester, also known as a pull tester or univeral testing machine (UTM), is an electromechanical test system that applies a tensile (pull) force to a material to determine the tensile strength and deformation behavior until break.
Cross head. The part of the Universal Testing Machine that moves up and down during the testing process. It can be powered by an electrical motor or a servo-hydraulic driver. Extensometer. Equipment capable of determining useful calculations like the Modulus of Elasticity, Secant Modulus and Poisson’s ratio.
15 de sept. de 2018 · The universal testing machine has two vertical threaded shafts. where the movable crosshead will slide on these vertical Bars. The Crosshead will be constant. These two heads will have locking clamps to hold the specimen in place. such as wires, rods, for mostly tensile test only.
