摘要
以兴安落叶松规格材的抗弯强度和抗压强度为例,介绍一种建立规格材强度性质间关系的方法,即采用两种强度具有相同累积概率的强度值来建立强度性质之间的关系。研究结果表明,抗弯强度和抗压强度的关系为幂函数关系。
Abstract A method of establishing the relationship between mechanical properties was introduced. The modulus of rupture and ultimate pompression strength of larch( Larix gmelini)dimension lumber(40 × 65 ×4 000 mm, 40 ×90 ×4 000 mm, 40× 140 ×4 000 mm) was tested. Using the strength values that have same cumulative probability to establish the relation between mechanical properties. The results indicated that the power function was the best model for discribing relationship between the modulus of rupture and ultimate pompression strength.
