This report deals with the experimental investigation of using large deformable FRP, ± 45° oriented fibers, in concrete-filled fiber tubes (CFFT) under axial cyclic compressive loading. In addition, this report presents finite element modeling (FE) of CFFTs with large rupture strain FRP (LRS-FRP). The LRS-FRP is made with polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) fiber...

Roy, Sylvain, Paolo Silacci, and Nikolaos Stergiopulos. Biomechanical proprieties of decellularized porcine common carotid arteries. Am J Physiol Heart Circ Physiol 289: H1567–H1576, 2005. First published May 20, 2005; doi:10.1152/ajpheart.00564.2004.—To analyze the effects of decellularization on the biomechanical properties of porcine common carotid arteries, decellularization was performed b...

The aim of this study was to investigate the applicability sugar beet pulp (SBP) in particleboard production as a substitute for wood material. Two variants board density, 650 kg/m3 and 550 kg/m3, containing 0%, 25% 50% SPB, were evaluated. During following features measured: modulus rupture (MOR), elasticity (MOE), thickness swelling (TS) water absorption (WA). results showed that boards up SB...

In this study, the effect of TiO2 when added to a mixture Nigerian sourced kaolin and calcined alumina powder (50:50) was investigated. The influence Ti4+ ion on physico-mechanical property (apparent porosity, bulk density modulus rupture), phase microstructural evolution studied at sintering temperature 1600?C mullitisation has been maximized based previous reports. sintered samples showed con...

ABSTRACT This study aimed to determine the concentration of condensed tannins in bark Mimosa tenuiflora (Willd) Poir trees. Additionally, physical-mechanical properties cross-laminated timber (CLT) panels bonded with an adhesive based on M. were assessed. Bark was collected from five The formulation synthesized by mixing powdered tannins, paraformaldehyde, and water at 50 °C under continuous st...

This paper presents and evaluates a new method for producing Slurry Infiltrated Fiber Concrete (SIFCON). A study was carried out to investigate the impact on mechanical properties of SIFCON, where several cubes, cylinders, prisms were cast compare proposed gradual traditional multi-layer using same mixing proportions: 6% straight steel fiber, cement, sand, 10% silica fume replacement, 2.4% supe...

To provide data and methods for analyzing stem mechanics, we investigated bending, density and growth characteristics of 207 specimens of fresh wood from different heights and radial positions of the stem of one mature Norway spruce (Picea abies L. Karst.) tree. From the shape of each stress-strain curve, which was calculated from bending tests that accounted for shear deformation, we determine...
