The number near a curve in Figures 10(a) and 10(b) stands for the strain rate
; and the numbers near a curve in Figures 10(c) and 10(d) represent the average corrosion degree, respectively.
Lajtai et al  investigated the effect of strain rate
on deformation for brittle limestone ductile salt rock.
As it is commonly known, most thermosetting polymers have a strain rate
and temperature dependence on their mechanical properties (Young's modulus, yield strain) [16,17].
Besides, the mechanical properties of nanoplates can also be influenced by factors such as size, temperature, and strain rate
In a variety of rock engineering and geophysical applications, such as earthquakes, mining, civil engineering, petroleum engineering, and physical geography, rock materials are in a dynamic loading state, where the strain rate
is in the range of [10.sup.-4] to [10.sup.3] [1, 2].
Both of the changes illustrated here, in the tensile tests on PP and the impact tests on PVC, could also have been created by keeping the strain rate
the same and changing the temperature at which the test was performed.
At present, these methods have been widely used in the study of the dynamic characteristics of engineering materials under high strain rate
like rocks, ceramics, and composites.
High strain rate
behavior of the thermoset polymers has frequently been investigated over the past decade [14-17].
These materials are increasingly being used in high strain rate
and impact applications.
2D derived strain and strain rate
are the newer techniques that are load independent and better markers of tissue deformation and regional ventricular function compared to TDI.
