    2018-11-13 · Fatigue crack growth in self-standing plasma-sprayed tungsten and molybdenum beams with artificially introduced notches subjected to pure bending was studied. Fatigue crack length was measured using the differential compliance method, and fatigue crack growth rate was established as a function of stress intensity factor. Crack opening under compressive stress was detected.

  • Fatigue Crack Growth in Plasma-Sprayed Refractory

    Once a crack has been initiated, thermal shock failure is controlled by the nature of the crack propagation through the material. The R ST parameter defines the propagation of inherent, pre-existing cracks in a refractory and for our materials the R ST parameter reflected the TSR damage observed in the experimental data ( f f0 and E/E 0 ).

  • Finite element investigation of the crack formation in

    2007-1-1 · When refractory materials are subjected to the industrial thermal cycles crack nucleation and propagation occurs resulting in loss of strength and material degradation. The formation of cracks decreases the velocity of ultrasonic pulses travelling in the refractory because it depends on the density and elastic properties of the material.
