About:

“Instrumented impact test is a versatile tool to study the energy related to fracture phenomena in engineering materials. Here the mode of fracture is Charpy impact. With the help of instrumentation attached to the impacting tips, force associated with different stages of fracture, namely crack initiation, propagation and final fracture is collected and plotted as force versus distance or fracture time. With the help of this plot various parameters, namely, maximum force during fracture (F_max), force during initiation of fracture, force at the end of fracture and corresponding energy values are extracted. It can also draw the conclusion on the type of the fracture. We can operate the machine according to ASTM E23 and ISO 14556 standards. We have two pendulums corresponding to 300 and 450 J. It can offer a force upto 50 kN during pendulum swinging.”

“The sample dimension is 56x10mm. Two varieties of notches namely A type notch with 45° angle (2 mm depth) and U type notch (2 mm width). We have a notch broaching unit for the said notch preparation. We have temperature bath both for high temperature (upto 200°C) and low temperature sample preparation (upto –50°C).”
