In the framework of adhesive bonding, assessment interfacial properties has an essential role in determining joints' global responses. Various surface preparations are available for each type metallic substrate. There plenty tests widely used mechanical characterisation to determine and few assess properties. For such a case, specific three-point bending test can be applied examine interactions...

In order to study the prevention of roadway roof bending, sinking, and breaking dynamic disasters such as appearance rock bursts, three-point bending experiments sandstone under different spans were carried out. By using stress loading system acoustic emission technology, characteristic parameters fracture process analyzed, precursory information was explored, evolution law damage based on char...
