  1. Obrem. in nihanje les.vlage Deformacija pri vlaž.zmanj. pri sušen.povečuje. Les –(ortotrop –ortogonalna anizotropija) anizotropen material Specif.lezenje-lesna podajnost Rela.lezennje- lezni koefic. MEHANOSORPTIVA DEFORMACIJA napetostni tenzor NAPETOST IN DEFORMACIJA Časovno se viskoznost pojavi kot lezenje Trije količ.med norma.napet. in norma.deformacijo in Trije količ.med strž.napetr. In striž. deformacijo LINEARNA VISKOELASTIČNOST Hookovzakon – napetost proporcionalna deformaciji (neod.od hitro.defor.) Newtnov zakon – napetost proporcionalna hitrosti deformacije (neod. od defor. same Trdnostni rač.σ = E*ε σ -silap/resek E – fak.proporcionalnosti ε – spec.deformacija Trdnost lastnost česa glede na največjo obremenitev, ki jo prenese deformacija Elastične (Uel)-reverz. Zadržane elastične (Uzad)-reverz. Vizkozne (Uv)-ireverz. Trdota lastnost trdne snovi, trdnega telesa glede na odpor proti vdoru drugega trdnega telesa
