Energy Absorbed At Fracture
Product Code : LSK-MTE-10507
Energy Absorbed At Fracture (SKU LSK-MTE-10507) is a small-scale, bench-mounting notched-bar impact tester that swings a pendulum through a specimen and reads the energy absorbed in joules. It introduces impact testing and resistance to crack propagation in materials labs at engineering colleges, polytechnics and training institutes. Science Lab Supplies manufactures the pendulum unit and its instrumentation at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and offers it from there to colleges, tender contractors and distributors.
Specifications
The impact tester's specification is broken down in the table below. In short, a pendulum hangs in a rigid frame on low-friction bearings with an angular encoder at the pivot, an electromagnet holds it at the start, and a separate instrumentation unit releases it and shows the energy absorbed, all behind an interlocked guard.

Applications and Experiments for the Energy Absorbed At Fracture Tester
Students compare how much energy different metals absorb when a notched specimen is broken by a single impact. The results show toughness and resistance to crack propagation, contrasting ductile and less ductile behaviour among plain carbon steel, brass, copper and aluminium.
- B.E./B.Tech mechanical and metallurgy: notched-bar impact test and material toughness, with notch depth and specimen width checked on a Vernier Caliper.
- Materials science practicals: comparing energy absorbed by ferrous and non-ferrous metals, with extra specimen lengths cut on a Hacksaw Frame.
- Diploma engineering and TVET: safe introduction to common impact testing techniques.
Standard Scope of Supply
The set comprises the main pendulum unit with guard, the instrumentation unit, the power supply, a specimen holder, lengths of plain carbon steel, brass, copper and aluminium, plus a hacksaw and a cutting jig. The jig keeps the notch position repeatable, so specimens made in the lab give comparable results.
Packing, MOQ and Lead Time
Pricing is available for one tester or a set for a larger materials lab. Each quotation lists packing, delivery time and price for that number of units, and extra material lengths or other test and measurement instruments in India from this range can be quoted alongside.
Science Lab Supplies, registered as an exporter with an Importer-Exporter Code, can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. An impact-testing bench can be quoted after you send the quantity through the contact page or add the tester to the enquiry cart; for bids, the lab tender page sets out the steps.
Frequently Asked Questions
How are test specimens made?
Lengths of each specimen material are included with a hacksaw and cutting jig, so the lab cuts its own notched specimens. The jig repeats the notch position, giving valid comparisons between tests.
Is the pendulum safe for student use?
The apparatus is fully enclosed by an interlocked guard over all moving parts, and release is controlled from the instrumentation unit. Tests should still be run under staff supervision.
Is Science Lab Supplies the actual manufacturer?
The pendulum frame, guard and instrumentation unit are produced at the company's Saha, Ambala facility, so specifications, quotations and supply are all handled by the maker of the tester.
What does the display show?
The instrumentation unit shows the pendulum's angular position before and after impact and directly displays the energy absorbed by the impact in joules, so no conversion from the swing angles is needed.
Related Material Failure Testers
Impact is one of several ways materials fail. These machines cover fatigue, creep, tension, torsion and pendulum impact with separate Charpy and Izod positions, so a department can build a complete failure-testing practical around this tester and price all of the equipment together on one quotation.
