Universal Testing Machine (UTM)

A universal testing machine is used to test the tensile stress and compressive stress of materials. It is named after the fact that it can perform many standard tensile and compression tests on materials, components, and structures. It has the following units

1.        Loading unit:

           In this unit the specimen is clamped and the desired load is applied. It consist of the following components:

•         Table
•         Table cover
•         Column
•         Screw drive
•         Upper and lower cross head
•         Upper and lower jaws
•      Upper and lower clamping handles

   2.      Control unit:

             This unit controls the motion of the jaws and application of load. It consist of the following components:

·        Automatic control

·        Manual control (hydraulic pump control, jaws up & down motion)

·        Dial gauge (load range selector,zero adjustment, span for calibration)
