Relationship between Modulus of Rupture and Ultimate Tension Strength of Dimensional Larch Lumber
The modulus of rupture(MOR) and ultimate tensile strength(UTS) of dimensional larch(Larix gmelinii) lumber were tested according to ASTM D 4761-1996.The probability density function was used to describe MOR and UTS data.The results indicated that logarithmic distribution had the best goodness of fit with MOR and Weibull distribution had the best goodness of fit with UTS.The relationship between MOR and UTS was established as a power function from the cumulative distributions of MOR and UTS.
