Abstract

The major engineering properties of Acer velutinum var. glabrescens wood growing in different regions of Caspian forests (North of Iran) was determined. Test materials were selected randomly from Acer velutinum var. glabrescens tree plantation and the test specimens were prepared according to ASTM D-143 standard. Mechanical and physical properties were measured on both green and air-dried samples (12% moisture content). The results of the measurement were statistically analyzed based on randomized block design and factorial experiment. The influence of specimen locations at different stem heights was examined. Based on the results of this study, Significant areas of habitat in the area, Maple Vysr Mazandaran species most resistant of the Maple Sangdeh Frame has the lowest resistance. Keywords: Maple, statice bending, compression parallel to grain, compression perpendicular to grain, tension perpendicular to grain, Acer velutinum var. glabrescens.
