Volume 23, Issue 2 , October 2008, , Pages 191-199

https://doi.org/10.22092/ijwpr.2008.117416

Abstract
  In this study beech wood steamed specimens were compressed longitudinally to bulk cell wall at three levels of 0, 10 and 15 percent relative to their original length, and some mechanical properties including MOE, MOR, E-value, tensile strength, and tensile strain were measured. The results have shown ...  Read More
