DETERMINATION OF MECHANICAL ANDPHYSICAL PROPERTIES OF MATERIALSBY ULTRASOUNDS

between bother the acoustic attenuation and reflection coefficients of longitudinal Ultrasonic waves propagated in samples having different case layer

In this article, we describe experimental studies, which were the work object at the Welding and Control Center (CSC), based on the measurement of some simple ultrasonic

Figure 5 : Source term calculated from the elastic problem for the first time step. The three coupled systems of equation were resolved and gave similar results to the

Third, the real-time measurements allow the direct calculation of changes in the biopolymers’ mechanical characteristics, e.g., stiffness and viscous losses, using the

Figure 6.24 shows the evolution of modulus and hardness (of the titanium carbide sample deposited with 5 SCCM of methane) as a function of the maximum penetration depth..

This work presents an investigation about the numerical determination of the mechanical behavior of braided architectures using geometrical modelling and subsequent

A factor analysis, using average weekly intake* for 33 food variables, reveals three principal components of the diet: satiating capacity, healthfulness and culinary complexity..

The influence of both the folding angle and the fold length are extracted automat- ically from a set of experimental values exhibiting a deterministic behavior and a variability due
