The Young's modulus E (MPa) was calculated as the slope of the initial part of deformation curve
In the tests, razor blade shear energy (N * mm) is calculated as the area under the force deformation curve
from the beginning to the end of the test.
At that point a load is reached that leads to crack development with a drop in the load deformation curve
in some test specimens.
The test specimens compressed in the dominating direction of the fibres (2nd direction) initially deformed more slowly and their deformation curve
at the initial compression stage was more upright.
The cyclic deformation curve
of the forged steel is independent of the geometrical direction (i.
The above analysis of clay deformation clearly indicates that based on the assumption of uniform deformation curve
of clay in effective stress-strain-time space, the residual deformation ([[epsilon].
For approximation of deformation curve
of the smooth sample with sixfold resharpening the power law hardening equation [s.
Hyperelastic constitutive models are used to represent the nonlinear elastic deformation curve
The deformation curve
consists of two quasi-lin-ear parts that differ in their slopes: the first one at the lower strains with a higher slope is the basis for determination of the modulus of elasticity, whereas the other one is characteristic for higher strains.
Besides, the shape of the cumulative AE events versus deformation curve
also depends on adhesion between phases.
We then loaded this beam in flexure to obtain the force versus deformation curve
for multiple specimens.
The energy values in this kind of discontinuous jump deformation are independent of the actual path of the deformation curve
and depend only on the end-points.
