In this paper, the ultimate stress, ultimate strain
and elastic modulus of single crystal [gamma]-TiAl alloy is analyzed based on the molecular dynamics method under different temperatures and vacancy concentrations, and the effects of temperature and vacancy concentration on the mechanical properties of the material are determined.
For the conservative estimation, ultimate strain
at compression fiber was assumed to be 0.
Failure was assumed to occur when local fiber strain reached the ultimate strain
of the tendon.

An increase in the moisture content of a specimen caused an increase in ultimate strain
and an associated decrease in minimum bending radius.
Fatigue preloading had the effect the decrease of ultimate stress, yield stress and ultimate strain
, with the increase of loading cycles number as results from figure 2 and relation (15).
With ultimate strain
capacities on the order of several percent, steel is widely used in construction due to its good ductility in tension.
Three key parameters affecting the shape and magnitude of stress-strain curve of concrete are the peak stress, the strain at peak stress, and the ultimate strain
For specimens subjected to 10% of corrosion damage, UDCGFRP of 3 mm thickness increased the ultimate strain
by 55% and the 5 mm thick UDCGFRP increased the lateral strain level by 72%.
Significant structural changes have probably occurred before that point, and due to the slightly different shape of stress-strain curves of weak specimens compared to stronger specimens, a yield strain close to and even larger than the ultimate strain
is sometimes found in weak specimens.
In the RPC prismatic specimens' uniaxial compressive strength test, the stress-strain curve displays a linear ascent stage until the ultimate strain
when the strength sharply drops, and then explosive failure occurs finally.
Some researchers investigated the effect of twist level on the tensile mechanical properties of the electrospun yams such as ultimate stress, ultimate strain
, elongation at break, and elastic modulus [1, 14, 16, 21, 23, 24, 32, 33].
