Oriented strand board (OSB) is an important engineered wood product manufactured through bonding of strands in cross-oriented layers. The bending strength, one the crucial properties for loadbearing material, OSB strongly depends on its structural characteristics. To understand strength OSB, strain distribution was continuously monitored during a three-point test using digital image correlation...

The mechanical and tribological properties in WC-Co coatings are strongly affected by hardness and elasticity specifications. The results revealed the effect of spraying distance on microhardness and elasticity modulus of coatings. The metallurgical studies have been made on coated samples using optical microscopy, scanning electron microscopy (SEM). Keywords—Elasticity modulus, HVOF, Micro-ind...

This paper analyzes the usability of different dynamic moduli of elasticity and wood density for the prediction of mechanical properties – static modulus of elasticity and modulus of rupture – in samples with grain deflection from the longitudinal direction. Five tropical hardwoods (Afzelia bipindensis, Intsia bijuga, Millettia laurentii, Astronium graveolens and Microberlinia brazzavillensis) ...

uniaxial compressive strength (ucs) and elastic properties of rocks play a major and vital role for the design of any engineering structure. the specimen diameter size is one of the main factors that influencing on ucs, elasticity modulus and poisson’s ratio (e and υ). here, an attempt has been made to investigate the effect of specimen diameter size on ucs, e and υ. moreover, we studied the co...

Abstract Low-grade yellow-poplar (Liriodendron tulipifera) graded No. 2 Common, and 3 Common (National Hardwood Lumber Association - NHLA rules) is mainly used by the industry to produce wood pallets. Cross-laminated timber (CLT) panels are options diversify usage increase value of this material. Therefore, objective study was CLT from a population 2A, 2B, 3A, 3B lumber evaluate whether panel p...

Abstract A deep-learning-based semantic segmentation approach (U-Net) was used to partition the anatomical features in cross-section of hinoki ( Chamaecyparis obtusa ) wood during a micro three-point bending test. Using Crocker–Grier linking algorithm, thousands cells were successfully extracted, and several parameters (area, eccentricity, fitted ellipse aspect ratio, bounding box ratio) evalua...

The objective of this study is to examine the mechanical performance cross laminated timber (CLT) panels made low-value sugar maple under out plane loads through tests and numerical simulation. laminations were sorted into High Low classes based on measured modulus elasticity (MOE). Two 3-layer CLT layups as High-Low-High Low-High-Low glued with resorcinol-based adhesive one layup melamine-base...

Bamboo is abundantly and vastly available, which known for its strength verity of usage. In this work, the effect acrylonitrile/MAPE/nano-clay on bamboo nanocomposites (BNCs) optimization were evaluated using response surface methodology (RSM). The developed BNCs characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), thermog...

This work highlights the effect of temperature on modulus elasticity following orthotropic axis six species tropical woods: assamela, bibolo, doussié, iroko, movingui, and sapelli scientific names Afzelia, Pericopsiselata, Distemonanthus benthamianus, Entandrophragma cylindricum, Miliciaexcelsa, Lovoatrichilioides, respectively. The four-point bending compression tests were conducted to determi...
