Triaxial variation of the modulus of elasticity in the thermo-elastic range of six tropical wood species

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 determine failure loads, which can help further performed in elastic domain. In order Young's thermoselastic field, above carried out at different levels loads temperature; samples 20 × 340 mm dimensions for 60 according current standards. strains read by means two strain gauges, connected gauge bridge. Test results under constant thermo-hydric conditions showed an increase longitudinal, radial tangential MOE all as increased from 22°C 40°C, a regression 40°C. terms lost modulus, due temperature, classification: movingui<sapelli<iroko≈bibolo≈assamela<doussie. Those may be crucial while selecting wood typical use range temperature.
