Self-camber of timber beams by swelling hardwood inlays for timber–concrete composite elements

Ceramic Inlays versus Composite Inlays

Acid etching and filled acrylic materials have been generating great interest in the past few years because of increased public demand for esthetic restorations and alternatives to amalgam. Composite resin and ceramic inlays, which use adhesive bonding, were introduced to make possible toothcolored restorations. The physical properties of composite resin restorations, and their poor wear resist...

Microleakage of Composite Inlays Luted with Self-adhesive Cements

Objective: To evaluate the microleakage of three self-adhesive cements and one etch & rinse resin cement on dentin and enamel interfaces. Methods: Forty-eight inlays preparations (n=12) with enamel and dentin margins were performed on extracted teeth. After impressions, indirect composite inlays were manufactured and luted with self-adhesive resin cements (RelyX U100, Maxcem or SpeedCem) or an ...

Design approaches for timber-glass beams

This paper relates to the mechanical performance of timber-glass composite beams, which take exceptional advantage of the combination of the materials involved. Beam bending tests were performed with beams made from float glass and heat-strengthened glass. Three different adhesive types were used: silicone, acrylate and epoxy. The test results show that, with a proper design, the timber is able...

investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
