Correlation among microfibril angle, density, modulus of elasticity,
modulus of rupture and shrinkage in 6-year-old Eucalyptus urophylla x E.
Caption: Influence of
Modulus of Rupture on Cracking This graph shows the influence of the
modulus of rupture (flexural strength) on the percent of slabs cracked as predicted by using the AASHTO Mechanistic-Empirical Pavement Design Guide.
NIR-based calibrations for the estimation of density, modulus of elasticity (MOE), and
modulus of rupture (MOR) were developed using clear wood samples obtained from several tropical, subtropical, and temperate pine species growing on two plantation sites in Brazil.
The modulus of elasticity and the
modulus of rupture during flexion could not be calculated for G5 and G6 as the intricate geometry of the structure did not allow the determination or application of a mathematical model that could accurately represent the physical state of the loads, geometry, boundary conditions and behaviour of the materials.

Modulus of Rupture for specimens with and without fibres
* RCC properties and typical relationships among compressive strength, tensile strength,
modulus of rupture, and modulus of elasticity are similar to those of conventional hydraulic cement concrete.

Modulus of rupture of fired bodies: The variation of the
modulus of rupture for different specimens with the three aforementioned parameters was investigated and the results obtained for 15 minutes soaking time shown in Figure 3f.
For flexural elements, concrete cracking is usually represented by the
modulus of rupture [3].
When average size of needle fibers was increased from 15 mm to 3 mm in the composites, the increase in internal bond strength,
modulus of rupture and screw withdrawal strength was 58, 4.4, and 7.6%, respectively.
