Investigations on flexural and tensile properties of GFRP laminates influenced by stainless steel wire reinforcement were carried out as a novel approach. Plain GFRP laminates and GFRP laminates reinforced with stainless steel wires at different depth with various pitch distances were fabricated by hand layup method. The composite specimens reinforced with steel wires were exposed to low freque...

PURPOSE The purpose of this study was to evaluate and compare the flexural strength and microhardness of provisional restorative materials fabricated utilizing rapid prototyping (RP), Computer Assisted Designing and Computer Assisted Milling (CAD-CAM) and conventional method. MATERIALS AND METHODS Twenty specimens of dimensions 25 mm × 2 mm × 2 mm (ADA-ANSI specification #27) were fabricated ...

Experimental results for quasi-static cyclic tests on reinforced concrete (RC) walls have shown that shear deformations can constitute a significant ratio of the total deformations when the wall is loaded beyond the elastic regime. For walls, which form a stable flexural hinge at their base, the ratio of shear to flexural deformations remains approximately constant over the entire range of impo...

Background and aims. The aim of this study was to compare flexural strength of specimens processed by conventional and injection-molding techniques. Materials and methods. Conventional pressure-packed PMMA was used for conventional pressure-packed and injection-molded PMMA was used for injection-molding techniques. After processing, 15 specimens were stored in distilled water at room temperatur...

Use of concrete paver blocks is becoming increasingly popular. They are used for paving of approaches, paths and parking areas including their application in pre-engineered buildings and pavements. This paper discusses the results of an experimental study conducted on Fly Ash Concrete with the aim to report its suitability for concrete paver blocks. In this study, the effect of varying proporti...

In this study, the flexural behavior of ultra-high-performance fiber-reinforced concrete (UHPFRC) is examined as a function of fiber length and volume fraction. Straight steel fiber with three different lengths (lf) of 13, 19.5, and 30 mm and four different volume fractions (vf) of 0.5%, 1.0%, 1.5%, and 2.0% are considered. Test results show that post-cracking flexural properties of UHPFRC, suc...

The aim of this study was to evaluate the effect of reinforcing polyaromatic polyamide (aramid) fibers with various orientations on the flexural properties of denture base resin. Aramid fibers with four orientations of unidirectional, woven, non-woven and paper-type were pre-impregnated and placed at the bottom of a specimen mold. Heat-polymerized denture base resin was packed over the fibers a...

In this paper, tests on flexural buckling ( Lateral – Torsional ) of cold-formed steel(CFS) lipped Channel beams under restrained boundary conditions are described Two point loading for flexural tests have been established for 3.0m span to obtain uniform bending moment. The section sizes selected for testing are 100x50x10 mm, 100x50x15 mm and 100x50x20 mm with 1.6mm and 2.0mm thickness for the ...

BACKGROUND Microwave postpolymerization has been suggested as a method to improve the flexural strength of an autopolymerizing denture reline resin. However, the effect of microwave postpolymerization on the residual monomer content and its influence on flexural strength have not been investigated. OBJECTIVES This study analyzed the effect of microwave postpolymerization on the residual monom...

Recently, new generations of nanoceramic composite resin CAD/CAM blocks, have been introduced to dentistry, which are claimed to have higher flexural strength, fracture, fatigue and wear resistance, and beside natural looking appearances can be polished easily. Therefore, the aim of this study was to compare flexural strength of 2 nanoceramic composite resin CAD/CAM blocks (Lava Ultimate and Vi...
