Acoustic Emission and Modal Frequency Variation in Concrete Specimens under Four-Point Bending
The Acoustic Emission (AE) and Dynamic Identification (DI) techniques were applied simultaneously, in an original way, to examine the stress dependent damage progress in pre-notched concrete beams tested in four-point bending. The damage mechanisms were characterized by analyzing the AE signals registered during the tests, conducted by increasing the specimen’s vertical deflection. In particula...
متن کاملCluster Analysis of Acoustic Emission Signals for Carbon/Epoxy Composite in Four-point Bending Test (RESEARCH NOTE)
Due to the extensive use of composites in various industries and the fact that defects reduce ultimate strength and efficiency during operation, detection of failures in composite parts is very important. The aim of this paper is to use Acoustic Emission (AE) non-destructive method in four-point bending test of carbon/epoxy composite to analyze and examine the failure mechanisms. This method is...
متن کاملOn the Characterization of Strain Hardening Cement-based Materials by Inverse Analysis of Bending Tests
An inverse analyses procedure for determining the mechanical material properties of strain hardening cement-based materials is presented. It allows to determine the uniaxial stressstrain curve up to the material’s localization point on the basis of the results of four-point bending tests. In these tests, the beam curvature is measured and serves as input value for the inverse analysis. An evolu...
متن کاملThree-Point Bending Tests of Zirconia Core/Veneer Ceramics for Dental Restorations
Introduction. The mechanical strength and the surface hardness of commercially available yttrium-doped zirconia were investigated. Furthermore, a comparative study of eight different ceramic veneers, to be used for the production of two-layered all-ceramic restorative systems, was carried out. Materials and Methods. Four types of zirconia specimens were analyzed, according to a standard ISO pro...
متن کاملThree-dimensional analysis of renal artery bending motion during respiration.
PURPOSE To evaluate displacement and bending of the renal arteries during respiration. METHODS Seven men (mean age 59+/-7 years, range 54-71) were imaged with contrast-enhanced magnetic resonance angiography (MRA). Two phases of the MRA were acquired during separate normal inspiration and expiration breath-holds. Displacement of the kidneys and renal ostia and changes in renal branch angle we...
