Diagram of the proposed algorithm for determining the elasticity modulus
from dynamic vibration tests and the finite element method.
S] were elasticity modulus
and sectional area of pre-stress tendons; E represented the elasticity modulus
of concrete; [I.
High value of elasticity modulus
is important for designed goods made from EOC composites.
It's notes from these figures that the (stress--strain) curves, It consists of elastic deformation zone represented by linear relationship between stress and strain in elastic region, from this region, it can be calculated the elasticity modulus
The ranking from the highest to lowest according to elasticity modulus
values is at the order of BHA, 5BHA, and 10BHA except for 1100[degrees]C before.
is generally determined on the basis of laboratory tests, in situ measurements or through analysis of the seismic velocity of the medium (dynamic modulus).
The bone elasticity modulus
is admitted equal to [E.
The subballast layer requires the soil mixture strength of at least 450-500 MPa (similar to the elasticity modulus
the crushed stone layer).
Based on the conducted research, the addition of the nanoparticles not only increases the hardness, elasticity modulus
, and toughness of the coating but also lowers its network density and converts the scratch morphology from fracture type to plastic type (self-healing capability).
In most cases, the cast post (the material with the greatest elasticity modulus
in this study) presented the minimum stress distribution towards the root, followed by the prefabricated titanium post and the fiberglass post.
Due to better homogeneity of lightweight concrete resulting from both excellent bond and comparable elasticity modulus
, the linearity of the ascending part is held up to 90-95% of maximum stress, while for normal weight concrete of the same strength class it is usually up to 30-45%.
The technological products for which the above elasticity modulus
was obtained present various shapes ranging from simple to complex (fig.
