Mechanical behaviour of sugar maple in cantilever bending under constant and variable relative humidity conditions

“…Experimentally, it has been determined that viscoelastic creep is strongly dependent on temperature and relative humidity, as well as the level of applied load. Different studies have shown that viscoelastic creep is much greater at high temperatures than at low temperatures (Kingston and Budgen 1972; Perré and Aguiar 1999; Ranta–Maunus 1993; Tazrout et al 2009; Wu and Milota 1995). The same effect has been observed with respect to relative humidity variations (Keith 1972; Moutee et al .…”

“…Creep tests have been conducted in tension (Hoffmeyer 1990; Wu and Milota 1995, 1996), compression (Hoffmeyer 1990; Wu and Milota 1995), bending (Bengsston 2001; Hoffmeyer 1990; Zhou et al 1999, 2000) and cantilever bending (Foudjet and Bremond 1989; Moutee et al . 2009; Perré and Aguiar 1999; Tazrout et al 2009). Many studies indicate that viscoelastic creep and mechanosorptive creep are greater in the perpendicular direction to the grain than in the parallel direction (Rantas-Maunus 1993; Tazrout et al 2009; Wu and Milota 1995).…”

For specific uses such as engineered wood flooring, it is important to determine the tangential and radial direction of creep.…”
