TEMPERATURE-CONTROLLED DEVICE FOR MIXED-MODE FRACTURE TESTS

摘要

The invention relates to a temperature-controlled device forfracture tests, comprising a sealed chamber (1) including testing means (2, 3, 4, 5, 11), a multimodal tool (8) for securing the specimen (10) to be tested and sensor means (6, 7) for sensing the temperature and relative humidity conditions inside the sealed chamber (1); and an air treatment unit (12) connected to the chamber by means of air inlets and outlets (20, 21). The treatment unit comprises a plurality of sections (13, 14, 15, 16, 17, 18, 19) placed in series, each including different temperature control means configured to alter the temperature and relative humidity conditions of the air flow passing therethrough until predetermined values are obtained, and electronic means for controlling the components of the device.
