in this study the effect of nano sized silica particles (nano-sio2) on the physical and mechanical properties of rice husk and old corrugated container (occ)-cement boards was investigated. modulus of rupture (mor), modulus of elasticity (moe), internal bonding strength (ib), density, water absorption and thickness swelling after 24 hours immersion in water and hardness were measured. results s...

Previous studies in Eucalyptus nitens have revealed favourable genetic correlations exist between acoustic wave velocity (AWV) in standing trees and modulus of elasticity (MOE), which can determine the suitability of trees for structural timber and/or engineered wood products. This study investigates the strength and stability of genetic variation in standing tree AWV across a range of environm...

in this study, to determine poisson’s ratio and modulus of elasticity of white seedless grapes during maturation, the fresh fruit samples were harvested from a vineyard at seven sequential weeks from 6th september to 18th october. in each run, six grape berries were randomly selected and the static loading test and digital photography were done together. considering true shape of the fruit and ...

Upstream identification of wood properties using non-destructive testing methods such as acoustic velocity (AV) measurements is important for optimizing allocation to mills or products. We evaluated the effectiveness field AV measurement tools in predicting lodgepole pine stiffness (modulus elasticity, MOE) measured by Silviscan on samples. was trees and logs from six sites Alberta British Colu...

Heat treatment is one of the environmentally friendly and cost-effective modification methods applied for improvements wood properties. However, influences exposure duration temperature should be known to provide balanced In this study, effect (80, 120, 150, 180, 210°C) (2, 5, 8 h) on longitudinal ultrasonic wave velocity, density, dynamic Modulus Elasticity-MOE (Edyn), MOE in bending, Rupture ...

this study was carried out to determine the effect of seed growing regions and loading speed on some mechanical properties of castor seed. these properties are used to design and improve related machines such as expeller that are used for extraction of oil from castor seed. mechanical properties of castor seed were expressed in terms of rupture force and energy, bio-yield force, apparent modulu...

Significant volumes of plantation hardwood are available in Australia to produce value-added engineered wood products such as cross-laminated timber (CLT). To validate the possibility utilising this resource, bending structural properties Eucalyptus nitens solid board and finger-jointed feedstock were measured. The studied CLT panels produced from lamellas subjected strength, stiffness, rolling...

In this study the effect of nano sized silica particles (nano-SiO2) on the physical and mechanical properties of rice husk and Old Corrugated Container (OCC)-cement boards was investigated. Modulus Of Rupture (MOR), Modulus Of Elasticity (MOE), Internal Bonding Strength (IB), density, water absorption and thickness swelling after 24 hours immersion in water and hardness were meas...

A novel non-destructive method has been developed to predict modulus of elasticity (MOE) logs using measurements taken from cores extracted discs. The trees were felled and cut into allow validation our method; however, similar results would be obtained if the standing trees. shows that a single core breast height is sufficient MOE logs, allowing early grading sorting for optimal use processing...
