Analysis of High-Frequency Vibrational Modes Through Laser Pulses,ecimens are monitored by laser sources focused on spots of the external surface. The main purpose is to identify in the crystal lattice mechanical oscillations in a frequency range higher than the Acoustic Emission (kHz) and comprised between MHz and THz. Such vibrational modes in the THz regime wil

Overview of the Effects of Process Parameters on the Accuracy in Residual Stress Measurements by Us (ESPI), in combination with hole-drilling. Using this kind of approach instead of adopting strain gage rosette, as usual, can be advantageous in view of the fact that costs and time of the measurement can be reduced. However it should be taken into account that several parameters involved in the wh

Near Weld Stress Analysis with Optical and Acoustic Methods,o probe compressive or tensile residual stresses from acoustic velocity measurements and optical interferometry is to measure strain induced by an external tensile load. It has been theorized that a compressive residual stress increases the elastic modulus and that an external tensile stress reduces

Fatigue Damage Analysis of Aluminum Alloy by ESPI,ect of fatigue damage on the macroscopic deformation behavior during a tensile test has been analyzed with the interferometric fringes. Resultant fringe pattern showed that the elastic compliance in the damaged area increased as the fatigue cycle before the tensile test (Pre-fatigue cycle) increased
