| Summary: | This work is devoted to the development of an experimental method for studying the energy
balance during cyclic deformation and fracture. The studies were conducted on 304 stainless steel AISE and
titanium alloy OT4-0 samples. The investigation of the fatigue crack propagation was carried out on flat
samples with different geometries and types of stress concentrators. The heat flux sensor was developed based
on the Seebeck effect. This sensor was used for measuring the heat dissipation power in the examined samples
during the fatigue tests. The measurements showed that the rate of fatigue crack growth depends on the heat
flux at the crack tip. |
