Capability Analysis for Modulus of Elasticity and Modulus of Rupture

2013 10th International Conference on Information Technology: New Generations, 2013
Sawn softwood timber is used as a structural component in house walls and roofs. Consequently, the consumption trends generally follow those of the housing industry. Therefore, Government imposes tough quality control and quality assurance on the timber industry to grantee product standard meets the specifications in building industry.

Prediction of Modulus of Rupture of Concrete

ACI Materials Journal, 2000
Tensile strength of concrete is an important parameter for determining deflection and minimum flexural reinforcement. Many design codes use the modulus of rupture as the cracking strength. Relations giving the modulus of rupture as a function of concrete compressive strength are based on tests on concrete with a compressive strength lower than 40 MPa ...

DISTRIBUTIONS OF MODULUS OF ELASTICITY AND MODULUS OF RUPTURE IN FOUR MILL RUN LUMBER POPULATIONS

Wood and Fiber Science, 2019
The modulus of elasticity (MOE) and modulus of rupture (MOR) of graded lumber populations are commonly modeled by normal, lognormal, or Weibull distributions, but recent research has cast doubt on the appropriateness of these models. Such modeling has implications for ultimate performance and efficiency of resource use. It has been shown mathematically

Grade verification of SA pine — bending, modulus of rupture, modulus of elasticity, tension and compression

The Southern African Forestry Journal, 2004
Synopsis The last verification of SA pine timber strengths was done in the early 1980s. Uses of the pine logs and the rotation periods have changed. This investigation was undertaken to verify the visual grade 5 grading rules of SANS 1783-2 (1997) on 36 x 111 mm specimen sizes. Qualified timber graders identified forestry areas with low-density SA pine.
