The aim of the presented study is to determine the relationship between mechanical parameters of selected wood species ( sp., L., L., L., Mill.) used for the production of hand tools and drumsticks and the grain deviation angle from the rectilinear pattern. Modulus of rupture (MOR), modulus of elasticity (MOE), elastic strain and work to maximum load (WML) in the three-point bending test were determined. The results obtained show that the values of all the mechanical parameters measured for hickory wood are higher than those obtained for domestic species. As the grain deviation angle from parallelism increases, the mechanical properties of all analyzed wood species decrease. The greatest influence of grain deviation angle on mechanical parameters was recorded for the work to maximum load values.
本研究的目的是确定用于生产手工工具和鼓棒的选定木材种类（山核桃木、白蜡木、桦木、枫木、杨木）的力学参数与直线图案的纹理偏差角之间的关系。测定了三点弯曲试验中的断裂模量（MOR）、弹性模量（MOE）、弹性应变和最大载荷功（WML）。所得结果表明，山核桃木测得的所有力学参数值均高于国产木材种类的值。随着与平行度的纹理偏差角增大，所有分析木材种类的力学性能均下降。对于最大载荷功值，记录到纹理偏差角对力学参数的影响最大。
