Device for determining law of characteristics of material e.g. aluminum, forming test tube during construction of buildings, has processor determining law of characteristics of material from determined profile of test tube by laser module

摘要

The device (1) has a traction or compression machine (3) receiving a test tube (2) and mechanically loading the test tube along a loading axis (30). A laser module (4) comprises a laser transmitter (41) and a laser receiver (42) arranged opposite to a laser emitter to form an observation axis perpendicular to the loading axis. The laser module is mounted in translation along the loading axis to allow a scan of the test tube to determine a profile of the test tube after loading. A processor (5) determines a law of characteristics of a material from the profile determined by the laser module. An independent claim is also included for a method for determining law of characteristics of a material forming a test tube.
