The use of this material is very popular because it has several advantages such as light, biocompatible, aesthetic, relatively cheap, low water absorption, easy to manipulate, polish and repair, [1,2,4,5] but this material is not yet ideal in fulfilling the mechanical requirements of a denture base because it has a relatively low impact strength, transverse strength, and modulus of elasticity
, making it more susceptible to failure during clinical use.
They can now produce high modulus of elasticity
concrete designs in the 4,000-7,000 ksi ranges," says Williams.
2 southern pine lumber: Part A, modulus of elasticity
. Wood Fiber Sci.
Nicholson and Bieniawski developed based on RMR as in put parameter, Sonmez developed empirical model using young modulus of elasticity
and RMR as input parameters, Beiki et al.
where: J(t,[tau]) = 1/[E.sub.c]([tau]) + C(t, [tau]) is the creep compliance resulted from a unit stress of concrete, E ([tau]) is the modulus of elasticity
and specific creep of concrete at age [tau], [t.sub.s] = [t.sub.0] is the time, at which the autogenous shrinkage strain starts developing.
Table 4 shows the results that were obtained from the previous tests to determine the modulus of elasticity
parallel to the grain for bending and compression.
where, when [[sigma].sub.d] [right arrow] 0, 1/a refers to the slope of the tangent when the curve passes the origin and physically refers to the initial dynamic modulus of elasticity
of frozen clay [E.sub.d max], and 1/b refers to the asymptote of the curve and physically refers to the maximum axial dynamic stress [[sigma].sub.d max].
As in the yield stress, the incorporation of photoselector additives in the formulations decreased the modulus of elasticity
of the films compared to the 3304 LLDPE reference film.
Influence of the aggregate type on the modulus of elasticity
The Student t-test was used to compare the means from the modulus of elasticity
and tension at rupture between GI x G2, G3 x G4 and G5 x G6.
It was revealed that filler content does not effect on EOC/WF tensile strength, but elongation at break, modulus of elasticity
of EOC/ WF and EOC/FS and tensile strength of EOC/FS vary significantly with filler content.
Key word: Maize, bending stress, modulus of elasticity
, shearing stress, specific shearing energy.
