RESISTANCE OF BIMETALLIC PLATES ON THE DYNAMIC CRACKING

摘要

Among multilayer materials flat products like plates are the most significant group of products. One of the most effective method of merging such products is the technology of explosive welding. Many authors [1÷9] have made researches which aim was the evaluation of mechanical properties of different multilayer product. The literature [2, 4÷6, 8] states that for multilayer's products the most critical area in the merging zone. To determine the technological properties of this group of materials are specially intended standards but none of them do not determine how to test the impact energy of such group of materials. This is difficult because of mechanical and plastical properties differences of both layers, but sometimes knowledge of this parameter is necessary. Therefore in this paper are presented results of such test, with macro and microscopic analysis of fracture and merging area.
