TENSILE TESTING MACHINE

MAKE DINESH SCIENTIFIC

DESCRIPTION:

A device used to test the tensile strength and compressive strength of materials is called a tensile testing machine, or universal testing machine (UTM). Below is a comprehensive explanation of its main elements and operations:

LOAD FRAME:

• The main structure that supports the machine. It consists of two vertical columns and a horizontal crosshead.
• The crosshead moved up and down to accommodate different sizes of test specimens.

LOAD CELL:

• A transducer that converts force into an electrical signal. It measures the amount of force applied to the specimen.
• Load cells are available in different capacities to suit various testing requirements.

GRIPS/FIXTURES:

• Devices used to hold the specimen in place during testing.
• Various types of grips are available depending on the material and shape of the specimen, such as wedge grips, pneumatic grips, and vice grips.

CROSSHEAD:

• The movable component of the machine that applies tension or compression to the specimen.
• It is driven by a motor, hydraulic system, or screw mechanism

EXTENSOMETER:

• An optional accessory used to measure the change in length of the specimen with high precision.
• It is used to determine strain and calculate material properties like Young’s modulus.

CONTROL SYSTEM:

• The interface that allows the user to set test parameters, control the movement of the crosshead, and record data.
• Modern machines use computer-based systems with software for data acquisition and analysis.

SAFETY FEATURES:

• Safety shields and emergency stop buttons to protect the operator during testing.
• Overload protection to prevent damage to the machine and specimen.
