Laminate Veneerler
 Estetik dental tedavilerde hastaların beklenti ve gereksinimleri günden güne artmaktadır. Dental estetik, kaybettikleri estetik görüntünün yeniden kazandırılmasında son derece önemli bir yer tutmaktadır. Hasta beklentilerinin bu denli yüksek olması, hekimleri daha materyaller kullanmaya hassas tedavi uygulamalarına itmektedir. veneerler hastalara görüntüyü kazandırma no...

A major concern affecting the efficient use of carbon fibre reinforced composite laminates in the aerospace industry is the low velocity impact damage which may be introduced accidentally during manufacture, operation or maintenance of the composite structures. It is widely reported that the contact behavior of composite laminates under low-velocity impact can be obtained under quasi-static loa...

We have investigated a series of high performance metal-matrix composites (MMCs), in order to improve mechanical and thermal properties such composites. To fabricate composites, we used spark plasma sintering (SPS) process. Using this processing, would minimize or avoid some risks damaging filler surfaces during processing. In article, also introduced are various kinds MMCs, metal/intermetallic...

Piezoelectric wafer active sensors (PWAS) are lightweight and inexpensive transducers that enable a large class of structural health monitoring (SHM) applications such as: (a) embedded guided wave ultrasonics, i.e., pitch-catch, pulse-echo, phased arrays; (b) high-frequency modal sensing, i.e., electro-mechanical impedance method; and (c) passive detection. The focus of this paper is on the cha...

Scatter dark field imaging with an X-ray grating interferometer has been implemented to probe the micro-structure of polymers, fibre-reinforced composites or light metals. The method has now been developed further to enable the characterisation of the fibre laminate structure. Experimental results obtained by scatter dark field computed tomography illustrate how information on the microstructur...

This paper focuses on parametric model order reduction (PMOR) of guided ultrasonic wave propagation and its interaction with damage in a fiber metal laminate (FML). Structural health monitoring FML seeks to detect, localize characterize the high accuracy minimal use sensors. can be achieved by inverse problem analysis approach, which employs signal measurement data recorded embedded sensors str...

This paper presents a 1 m long self-deployable boom that could be folded around a spacecraft. Previously developed simulation techniques are used to analyze this two-hinge boom, made from two-ply plain weave carbon fiber laminate. A stress-resultant based failure criterion is used to study safety of the structure during both stowage and dynamic deployment. A safe design that latches without any...
