The present work study flexural and tensile behavior of short Kenaf fiber reinforced composites. The fibers are chemically treated in 2% NaOH solution at room temperature. Short fibers of 4mm and 8 mm are used in the present work. The composite lamina is prepared by hand molding using isopthalic polyester resin. Flexural test and tension tests are carried out as per ASTM standards. The flexural...

BACKGROUND This study aimed to evaluate the flexural strength and microhardness of three different anterior composites after 10 000 thermocycles. MATERIAL AND METHODS The mechanical properties of a nano-fill composite (Filtek Ultimate Universal Restorative (FUR) (Enamel)), a nano-hybrid composite (Clearfil Majesty ES2 (ES2) (Enamel)), and a micro-hybrid composite (G Aenial Anterior (GAA)) wer...

A temperature-like parameter is introduced in ordinary sandpiles models. A temperature dependent probability distribution is assigned for the sand toppling on sites of any height. In mean eld theory criticality is obtained for all the values of temperature and no characteristic avalanche size appears. Numerical simulations supports the existence of criticality at any temperature with apparently...

BACKGROUND Most study concerning the prevalence and dermatological manifestations of the extrinsic and the intrinsic form of atopic dermatitis (AD) were performed in children and adult AD related to the early-onset AD extending to adult life. Adult-onset AD is a subgroup of AD. Apart from the typical eczematous flexural distribution pattern of AD, this group may also have nontypical morphology ...

objective: despite great advances made in dental composite resins, their use is associated with some concerns regarding their mechanical properties such as their flexural strength. considering the introduction of different composite resins into the market, there is a need to compare their mechanical properties and particularly flexural strength. this study aimed to compare the flexural strength...

The abelian sandpile models feature a finite abelian group G generated by the operators corresponding to particle addition at various sites. We study the canonical decomposition of G as a product of cyclic groups G = Zd1 ×Zd2 ×Zd3 · · ·×Zdg where g is the least number of generators of G, and di is a multiple of di+1. The structure of G is determined in terms of the toppling matrix ∆. We constru...

OBJECTIVES To measure the flexural strengths and moduli of endodontic post materials and to assess the effect on the calculated flexural properties of varying the diameter/length (D/L) ratio of three-point bend test samples. METHODS Three-point bend testing of samples of 2mm diameter metal and fiber-reinforced composite (FRC) rods was carried out and the mechanical properties calculated at su...

Evaluation of the ultimate strength for UHPFRC (ultra-high-performance fiber-reinforced concrete) flexural members was conducted. In this study, an experimental program about beams conducted with effect fiber volume fraction, shear span to depth ratio, and compressive matrix as main variables. Among them, it found that fraction variable had greatest influence on strength. The inclusion 2% steel...
