What is Tensometer?
Tensometer is a device used to determine the reaction of the material to different trunks called load. The amount of stretching that has the material when it is under voltage provides important information about tensile strength and fatigue. Tensometer devices are commonly used in the manufacturing industry to ensure that parts meet the necessary strength and endurance requirements.
TENSOMETER The device consists of two grips that hold part of the test material in place. These handles are then used to apply tension or compression force called load, for a test piece. Tensometer devices can create force using a screw or hydraulic ram that are driven by mechanical or electric agents.
The closed chambers can be used to place the strainthra. This configuration allows testing the characteristics of the material stress at specific temperatures and pressures. This is decisive for testing metals used in aircraft and submarines that can experience drastic changes in atmospheric pressure. KoMory is also useful for testing materials that will be exposed to high -temperature ranges.
The exact results from the Tensometer device depend on the quality of the test piece. Any defect that is created during the cutting process can distort test results and lead to premature voltage failure. Even the smallest inconsistency of the surface can grow quickly and spread under tension, leading to early fractures and metal fatigue. This is the same process that causes poorly produced rivets and metal foils to make fatigue and failure on aircraft when the atmospheric pressure is repeatedly exposed.
The results created by Tensometer provide loads as an extension function. From these data, along with the cross-sectional area of the test piece, the voltage curve can be carried. This curve is unique for each and provides key measures. These measures include elastic lIMIT material, proportionality limit, yield force and final force.
Tensometers allow engineers to determine the young module for the tested material. Young's module is the initial linear slope of the stress voltage curve, defined as tensile strength divided by tensile voltage. The tensile strength is determined by the division of the force applied by the cross -sectional area of the test piece. The tensile voltage represents the amount of stretching produced, divided by the original length of the test piece. The materials exposed to the Young module, the initial linear part of the voltage curve-cod, when the load is removed, returns to its original state.
Thepoint at which the stress voltage line begins to curl is the elastic limit of the material. The voltage caused by the load greater than this limit will lead to the permanent deformation of the material, which prevents it from returning to its original state when the load is removed. The maximum strength or voltage absorbed by the material represents its final power. This could orIt does not have to equal the strength of the fracture of the material.
