ANALISA UJI IMPAK CHARPY DENGAN PENDULUM YANG DIPASANG SENSOR STRAIN GAUGE

Abstract

In planning for a construction carried out in several stages. One of them is to choose materials that will be used by the mechanical properties of a material. To determine the mechanical properties of a material one of which is by way of impact testing. Impact test tool is a tool used to measure the material ductility or brittleness of the material to sudden load. This test equipment including the type of Charpy. The working principle of this impact test tool is to give the imposition of a sudden the specimen to be tested is static. By testing the known bias absorbed energy prices and the impact of suatubahan. For ease of implementation, the impact testing digital systems use measuring devices are indispensable. Impact test machine that exists today which, in determining the impact energy is through manual calculation. Therefore in this study a modification of the impact test equipment with the addition of digital measuring devices (strain gauge).

Keywords: charpy impact test, energy, impact value, digital, strain gauge.
