Experimental Investigation and Numerical Simulation of the Mechanical Behavior of a Novel Honeycomb Core Sandwich Panels Formed by Hydroforming Process
Sandwich panel with central core honeycomb aluminum as one of the main shielding structures because of their high strength-to-weight ratio and improved energy absorption capacity, has been attracted the attention of many researchers and practitioners in recent years. This paper initiates and presents a new type of central core honeycomb formed by hydroforming process. The study is augmented by ...

متن کاملQuasi-static Punch Indentation of a Honeycomb Sandwich Plate: Experiments and Modelling
Punching experiments on wide honeycomb sandwich beams were performed to evaluate the predictive capabilities of a newly developed constitutive model in structural applications. The employed constitutive model for plastically com-pressible orthotropic materials accounts for both non-uniform hardening and softening associated with stressing in different directions. This feature is vital when asse...
متن کاملDevelopment of a portable mechanical hysteresis measurement and imaging system for impact characterization in honeycomb sandwich structures
Honeycomb sandwich materials are commonly used for aero-structures, but because the outer skins are typically thin, 2-10 plys, the structures are susceptible to impact damage. NDI methods such as tap tests, bond testers and TTU ultrasound are successfully deployed to find impact damage, but identifying the type/degree of damage is troublesome. As the type/ degree of impact damage guides decisio...
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...
