This work concerns basic research on the concept of wood hardness in a sense similar to Brinell or in the modified sense of Monnin. The experimental part of this article is based on research carried out on beech wood with six indenters: three ball indenters of 10, 15 and 30 mm and three cylindrical indenters of 10, 15 and 30 mm. On the basis of measurements for a wide range of loads, relations analogous to Meyer power law of were obtained, with the exponent determined both for balls equal to 5/2 and for cylinders equal to 3/2. These exponents turned out to be exactly the arithmetic mean of exponents for ideally elastic and ideally plastic bodies. On this basis, new hardness formulae were proposed, taking into account Meyer law and the diameters of indenters. Therefore, the proposed two hardness formulae (for the ball and cylinder) are a generalization and development of Meyer hardness law.

尝试根据迈尔定​​律统一木材的布氏硬度，扬卡硬度和莫宁硬度

这项工作涉及对木材硬度概念的基础研究，其含义类似于布氏或蒙宁的含义。本文的实验部分基于在山毛榉木上使用六个压头的研究：三个10毫米，15毫米和30毫米的球形压头和三个10毫米，15毫米和30毫米的圆柱形压头。根据各种载荷的测量结果，获得了类似于Meyer幂定律的关系，并确定了等于5/2的球和等于3/2的圆柱的指数。这些指数恰好是理想弹性体和理想塑性体的指数的算术平均值。在此基础上，考虑了迈尔定律和压头直径，提出了新的硬度公式。因此，
