Application of Thermography in Analysis of Fatigue Strength of Materials and Structures
Thermography is becoming more and more relevant method in industry and as a research tool. It is an accepted method in many fields where non-destructive testing is carried out. In this paper focus was on evaluation of stress concentrations and fatigue of metal structures. Three thermographic methods: Thermoelastic stress analysis, Risitano method and acquisition of plastification zone and fract...
متن کاملImprovement of Fatigue Strength of Light Metallic Materials by Cavitation Shotless Peening
Cavitation normally causes severe damage in hydraulic machinery such as pumps, valves and so on. However, cavitation impact can be utilized to surface treatment to improve fatigue strength of metallic materials in the same way as shot peening. A peening method using cavitation impact was named as “cavitation shotless peening” or “cavitation peening” as shots are not required. As increase of sur...
متن کاملCompressive Strength and Compressive Fatigue Limit behavior of Two Fluoride releasing materials
This study was conducted to evaluate the compressive strength, compressive fatigue limit and the amount of fluoride released from the Smart Dentin Replacement SDR TM restorative material in comparison to another fluoride released from hybrid resin composite material Tetric N Ceram. A total of eighty (80) specimens were used in this study, where forty (40) specimens were used to evaluate the com...
متن کاملUltra-strength materials
Recent experiments on nanostructured materials, such as nanoparticles, nanowires, nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of ‘‘ultra-strength” phenomena, defined by stresses in a material component generally rising up to a significant fraction > 1 10 of its ideal strength – the highest achievable stress of a defect-free crystal at zero temperature. While conven...
متن کاملMechanics of Ultra - Strength Materials
167 Abstract Recent experiments on nanoscale materials, including nanowires, nanopillars, nanoparticles, nanolayers, and nanocrystals, have revealed a host of “ultra-strength” phenomena, defined by stresses in the material generally rising up to a significant fraction of the ideal strength—the highest achievable strength of a defect-free crystal. This article presents an overview of the strengt...
