RISVibration-Based Structural Damage Identification under Varying Temperature Effects
Publisher: American Society of Civil Engineers
Abstract: Vibration-based methods are promising for damage identification; however, their capabilities for damage identification under temperature variations are usually limited. In the paper, a vibration-based nondestructive global ...
Research of Dynamic Stress Concentration of Lined Cavities under Incident Plane SV Waves in Different Angles
Publisher: American Society of Civil Engineers
Abstract: An analytical series solution for dynamic stress concentration of lined cavities in a half space under incident plane SV waves was given by using wave function expansion method. The infinite series was cut and calculated ...
In Situ Acoustic Emission Investigation of Asphalt Fracture Process and Damage Quantification for Different Asphalt Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The identification of cracking damage and the dynamic diagnosis of damage evolution are of great importance to prolong the service life of asphalt mixture materials. Acoustic emission (AE) can identify the formation and ...
Experimental and Numerical Investigation on the Influence of Thermally Induced Stress Gradients on Fatigue Life of the Nickel-Base Alloy Mar-M247
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Today's and future parameters of stationary gas turbines and aircraft engines require intensive and highly efficient cooling of hot gas path components. High temperature and thermally induced stress gradients with impact ...
