Abstract When stress in concrete exceeds certain threshold value, microcracks are nucleated, these can propagate and coalesce forming macrocracks, resulting the gradual decay of mechanical properties eventual failure structures. For safety concerns, one needs to develop suitable nondestructive testing methods capable detecting past overloads structures during its service life. In this work, stress-induced damage is monitored using ultrasonic techniques, exploiting coupling between level...
Structural failure caused by corrosion of the reinforcing steel in concrete structures is quite common. In most cases, cracks appear on surface at a late stage, leaving inadequate time for taking any measures. This paper investigates detection damage reinforced elements using nonlinear ultrasonic (NLU) techniques. Various linear and NLU techniques were adopted to identify sensitive technique parameters induced its early stage. It observed that are not very effective detecting damage. The...
It is shown in this paper that the conventional triangulation technique not very reliable for locating impact point even isotropic plates when sensors are placed close to of strike two reasons: First, it difficult pinpoint exact time arrival signal and, second, Lamb modes a plate dispersive. Dispersive signals attenuate differently at various frequencies and propagate with different speeds causing distortions received signals, thus introduce error flight measurement. The assumes wave all...
In this article, a holistic technique for sensing damage initiation, as well progression in composite plates, is presented combining linear and nonlinear ultrasonic techniques. For investigation, multiple sets of plate specimens made two different materials were fabricated to check if the proposed works types specimens. The damaged by impact loading then inspected propagating Lamb waves through them. Different failure mechanisms, such fiber breaks, matrix cracking, debonding, delamination,...
