MATERIALS LABORATORY WITH DATA CAPTURE

A hydraulic tensile and Brinell hardness testing machine. The machine tests any suitably shaped specimens of various materials. The material must not exceed the maximum strength or hardness limits (see ‘specifications’ on the data sheet). TecQuipment also supply additional low-cost test specimens (available separately).

The main parts of the equipment are: 

• A load frame
• A display unit with a digital display of force (load)
• A ball indenter for Brinell hardness tests
• An extensometer with a digital display for tensile tests

The load frame is mounted on adjustable legs and can be fixed to a bench for stability. To apply loads, students pump a handle connected to a hydraulic ram.

The display unit shows force and works as an interface to send data to a suitable computer. The extensometer has a digital display of extension and connects to the display unit for data capture.

Included is TecQuipment’s MF40 MKII software to allow students to use the equipment with a computer (computer not included). The software records the data and produces detailed graphs of force against elongation and stress against strain.

Typically students will work in small groups, with one student working the hydraulic ram, while others note readings or use the software.

To do a hardness test, students put a hardness specimen on a platen and lock a guard in position. They apply a suitable load with the ball indentor and measure the impression in the specimen. They then use an equation to calculate Brinell hardness.

To do a tensile test, students fit a specimen to the machine, attach the extensometer to the specimen, and zero the display unit and extensometer. They then lock a guard and apply loads, taking various readings, until the specimen breaks. Students use the results to find the ultimate tensile strength, the proof stress and Young’s modulus of the material.

The Materials Laboratory comes with a user guide that shows experiment methods, information, references and tips.

• DefleX® a complementary tool designed to introduce students to the concept and technique of Digital Image Correlation (DIC). This product is compatible with our DefleX®-2D product that uses one video camera and our DefleX®-3D product that uses two video cameras to track the movement of materials during a dynamic event. They are complete and compact systems for measuring full field displacements and strains over a material’s surface in two and three dimensions, offering students a digital blended learning experience as part of their engineering courses.
