Title: Drying Stresses in Red Oak: Effect of Temperature

Abstract: The effects of kiln drying at 80° to 140° F. and controlled room drying at 35° and 80° F. on tensile and compressive stresses, perpendicular to grain, in 2-inch red oak are reported. Increasing temperature tended to increase maximum tensile strain in the outside layers at the start of drying and maximum tensile strain in the center layers after stress reversal. Maximum compressive strain in the center layers was about the same at most temperatures but considerably lower at 140° F. Temperature had little effect on tension set in the outside layers. The greater compression set in the interior layers at higher temperatures resulted in significantly greater board shrinkage.
