Resilient modulus estimation system
… software tool developed for estimating resilient modulus of subgrade material, predicting field moisture content for different combinations of environmental and pavement related factors, and modifying resilient modulus values based on changes in moisture contents. Subgrade resilient modulus is a …

High modulus carbon fiber/titanium laminates
… were fabricated using inorganic matrix/high modulus carbon fiber composites with titanium sheets. Laminates were tested in three-point bending to assess the performance of the upgrade. The results show that combining Geopolymer high modulus carbon composites with titanium sheets significantly …

Comparison of Shear Modulus Test Methods
… between E:G ratios are due to the shear modulus terms. This research has shown differences in shear moduli results of the three test types (ASTM D 198 torsion, ASTM D 198 three-point bending, and the FPBT). Differences in the average E:G ratios per material and test type were also …

Low temperature bulk modulus of solid argon
… in this pressure range, give a P=O, T=O bulk modulus of 28.8±0.4 kbar. This value is in good agreement with the value obtained by extrapolating recent piston-displacement measurements to P=O and also with recent theoretical calculations which incorporate three-body forces. A comparison with …

Flexure modulus of elasticity in living branch wood
… of localized tree impacts on targets. Flexure modulus of elasticity (MOE) can be defined as an object's tendency to be deformed elastically, or not permanently, when a force is applied to it This research measures flexure modulus distally along the length of the branch as well as identifies key …

Properties of p-modulus on radially symmetric infinite trees
On a finite graph, the p-modulus of a family of paths takes the form of a standard convex optimization problem. The optimal value of this problem provides information about the underlying graph, and has been shown to be closely related to several important graph theoretic quantities including …

On Dynamic Modulus of Asphalt Concrete for Moisture Damage
Dynamic modulus (E*) test has gained substantial acceptance in recent years for evaluating Hot Mix Asphalt (HMA) rutting and fatigue cracking performances. Indeed, the recently developed Mechanistic Empirical Pavement Design Guide (MEPDG) uses E* data for stress and strain calculation, and E*-based …

The effect of lattice vacancies on the elastic modulus
… effect of quenched-in vacancies upon the elastic modulus of aluminum ma investigated. Equipment for dynamically measuring the change in elastic modulus was developed for the purpose. It was demonstrated that the presence of lattice vacancies will reduce the elastic modulus. This change in elastic …

Shrinkage & Modulus of Elasticity in Concrete with Recycled Aggregates
… coarse aggregate affected compressive strength, modulus of elasticity, and shrinkage in concrete when natural coarse aggregates were replaced with RCA. Concrete batches were made with water-cement (w/c) ratios of 0.30, 0.45, and 0.60, and substitution percentages ranged from 0% to 100% of natural …

Shear Modulus Degradation of Liquefying Sand: Quantification and Modeling
… to quantify the degradation of a soil's shear modulus as it undergoes liquefaction would help engineers design more reliably and economically. This thesis uses ground motions recorded by an array of downhole accelerometers on Port Island, Japan, during the 1995 Kobe Earthquake, to quantify the …

Exploring the Black Space of Compressive and Shear Modulus
<p>Uniaxial dynamic modulus is a standard test used to determine the viscoelastic behavior of asphalt pavement materials, with the standard analysis generating a Master Curve. One alternative to the master curve approach is a Black Space diagram, which is a rheological plot that can delineate …

A Novel Material Modulus Function for Modeling Viscoelastic Materials
… into finite element models. In metals, the modulus of elasticity can be modeled as a constant. That is, the modulus of elasticity is not treated as a function of frequency in dynamic models. For viscoelastic materials, the modulus of elasticity can be assumed to be constant for static forces …
