摘要 Tensile tests parallel to the grain were carried out on LV mode in an environmental scanning electron microscope(ESEM)chamber on Picea jezoensis var. microsperma sample. Displacement and strain fields for different load levels under proportion limit were obtained from digital image correlation method(DSCM). Heterogeneous microstructural influence on mechanical properties of wood were analysed.
