Cluster 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 کاملconstruction and validation of a computerized adaptive translation test (a receptive based study)
آزمون انطباقی رایانه ای (cat) روشی نوین برای سنجش سطح علمی دانش آموزان می باشد. در حقیقت آزمون های رایانه ای با سرعت بالایی به سمت و سوی جایگزین عملی برای آزمون های کاغذی می روند (کینگزبری، هاوسر، 1993). مقاله حاضر به دنبال آزمون انطباقی رایانه ای برای ترجمه می باشد. بدین منظور دو پرسشنامه مشتمل بر 55 تست ترجمه میان 102 آزمودنی و 10 مدرس زبان انگلیسی پخش گردید. پرسشنامه اول میان 102 دانشجوی س...
Using the Finite Element Analysis Method to Study the 3-point Bending Test for the Characterization of the Adherence
An elastic finite element analysis was conducted to evaluate the stress distribution in the initiation zone of the adhesive rupture during the 3-point bending test. This test is used to measure the adherence between a polyepoxy adhesive and aluminum alloy with different surface treatments. The purpose is to compare, in the high stress concentration areas, the stress fields calculated using fini...

متن کاملFour point bending setup for characterization of semiconductor piezoresistance.
We present a four point bending setup suitable for high precision characterization of piezoresistance in semiconductors. The compact setup has a total size of 635 cm(3). Thermal stability is ensured by an aluminum housing wherein the actual four point bending fixture is located. The four point bending fixture is manufactured in polyetheretherketon and a dedicated silicon chip with embedded piez...
