In addition, different correlations have been determined between the PFWD and FWD back-calculation moduli
(Steinert et al.
The knowledge of longitudinal and shear waves velocities allow to calculate values of dynamic elastic moduli
. Dynamic elastic moduli
one can assign from the relations (Plewa, 1992; Burger, 1992):
Since the water/cement ratio of laterized concrete influences its strength; it can be reasonably inferred that the water/cement ratio influences the moduli
of elasticity and deformability of laterized concrete at different degrees.
An opportunity to construct an analytical representation of the elastic moduli
data evolved recently from an extensive compilation (NISTIR 6853) of the elastic property data for polycrystalline oxide ceramics .
At the temperature of 15,20, and 60[degrees]C, moduli
of HMACPRM were 13% ~18%, 1% ~7%, and 4% ~7% bigger than those of HMAC-PRS and moduli
of HMAC-PRS were 4%~7%, 10%~20%, and 4%~7% greater than that of HMAC-RA, respectively, which means that PRM has the most significant effect on improving modulus of asphalt mixture.
The changes in the moduli
of the material as a function of temperature and time can be monitored from the DMA testing and thus allow the determination of the effects of these changes on the material.
Spaces and Arithmetic Geometry (2004: Koyoto, Japan) Ed.
Taken as a whole, the elastomer slabs prepared by CM have slightly decreased durometer, tensile strength and moduli
, and increased elongation compared to the slabs of the same materials prepared by LIM.
It was observed that the storage and loss moduli
were equal during sudden stiffening of the polymer.
The freezing moduli
of casting ([M.sub.c]), obtained from step 12, while "k's" value (ratio of modulus) is selected from steps 1, 8, 10 and 11 and feeder shape from 13.
Ceiling performance temperatures for selected moduli
are given in the Table.
Of particular interest are the test methods to determine the in-plane shear moduli
of both solid wood and wood-based composites.
