Description
The experimental setup is intended to study the strength and durability of structural materials under combined energy loading, which includes:
- compressive loads;
- tensile loads;
- induction heating;
- ohmic heating;
- electromagnetic oscillations;
- shock ultrasonic oscillations.
The setup is equipped with computer-aided measuring systems. The plastic deformation behavior is assessed using acoustic emission and internal pressure measurement methods.

Capabilities
The setup makes it possible to determine the short- and the long-time strength, to conduct thermocyclic tests, and to measure material characteristics (internal friction and heat conductivity).
Advantages
The setup provides:
- combined energy loading to intensify treatment processes that trigger self-organizing processes in structural materials (Ukrainian patents No 46841 of 11.01.2010 and No 56740 of 25.01.2011);
- computer-aided load and temperature control;
- acoustic emission monitoring of deformation processes.
