Tensile testing machine, also known as Tester, is used to check the tensile strength of a material, which includes fiberglass, stainless steel, aluminum, etc. The strength of a material is expressed as a property that is deformed at constant load. Materials can be tensile if they have the ability to be stretched to a specified length under strain. To measure the tensile strength, various machines are used such as tensile torsion, tensile stress, tensile strain, and tensile analysis machine. It has various advantages over other tests such as strain gauging, creep testing, dynamic testing, and static testing. It is usually performed by majority of the industries.
There are different types of Tensile Testing Machines available in the market, which includes tensile tester machines, multi media stress, and multi media tensile stress tester machines. All the machines are built to give accurate results and acceptable service. The machines are classified into two categories, which are classified according to the tensile strength rating. First type is classified as load-bearing. Second type is classified according to the tensile strength rating at single meter. The machines with higher load-bearing capacity are used for heavy industrial applications.
The tensile testing machines include a load cell, a fixed beam system, a device for measuring tensile force, and a control system. The load cell is generally made up of a source of external magnetic force and an armature for connecting the machine arms with each other. The internal mechanism of the machine includes fixed armature, fixed beam system for measuring the tensile force, and a source of external magnetic force. External magnetic force measuring devices are widely used for tensile measuring devices. These devices come with different types of control methods, like PZT, EEG, or linear armature.
Testers use different methods to evaluate the strength of the material where it is being tested. Some use tensile testing machines with load cells, while others use spring tester with adjustable spring forces. Many machines are based on the concept of tensile strength. As a matter of fact, all materials undergo some kind of tensile testing. Materials such as steel, fiberglass, aluminum, iron, and carbon fiber have been subject to tensile testing over the years.
Many manufacturers produce Tensile Testing Machines. A popular manufacturer of this type of equipment is Ideal Co., which is one of the largest manufacturers of machine tool and die industry. This manufacturer offers both portable and stand-alone Tensile Testing Machines. They also offer a wide variety of accessories, which can be used to evaluate Tensile Materials. A popular accessory offered by them is the universal testing machine, which can be used in a wide variety of applications.
A universal Tensile Testing Machine consists of a pump and two or more load cells. The load cell acts as a source of hydraulic or mechanical force measuring elements, which are arranged around the chamber. A hydraulic armature pumps the fluid through the load cell to generate an alternating magnetic field. The two major measurement components of a Tensile Testing Machine are the tensile force measuring device and the load cell.
The tensile testing machine results display an interpretation as a value associated with the applied load cell and/or tensile strain. The values may include: tensile strength, breaking strength, creep resistance, etc. A Tensile Test Machine allows the user to analyze and monitor tensile strength, fatigue life (in time), toughness, creep, and tensile strength in any type of material. It is also helpful for quality analysis.
Many industrial companies utilize a Tensile Testing Machine in order to obtain data related to tensile strength. For example, an aircraft producer may utilize the machine to determine the tensile strength of various load frames. This machine is also utilized in the measurement of strength, toughness and the thermal conductivity of various materials. It is also utilized to measure and determine the hardness of materials such as steels and pure copper. Many industries that utilize this machine are the following: aerospace, automobile, chemical, power generation, and many others.
